1.  Purpose of This Document                                                  
                                                                              
    This document is a cumulative summary of comments concerning the          
Magellan MIDR data set published on CD-ROMs.  It contains comments on         
all the MIDR CD-ROMs published so far.  Comments include information of       
interest to users of the data and notes about any known errors on the         
CD-ROMs.                                                                      
                                                                              
2.  General Comments                                                          
                                                                              
2.1  Normalization of Data                                                    
                                                                              
    Note that the eight-bit digital numbers (DN's) for each MIDR pixel        
on the CD-ROM's were computed by taking the estimated backscatter cross       
sections, dividing the values by the value for the Muhleman scattering        
law at the same incidence angles, converting to decibels, and scaling         
to bytes.  The Muhleman Law has the following expression:                     
                                                                              
        sigma naught = A cos(i) / (sin(i) + B cos(i)) ** 3                    
                                                                              
Values for A and B were meant to be 0.0188 and 0.111, respectively            
Through an error, the A value used for the Muhleman Law estimate              
was 0.0118.  As a result of this mistake, the pixel values are                
systematically about 10 DN (2 dB) greater than they should be according       
to the planned algorithm.  Also, because of an indexing error, the            
incidence angles used in the above equation were 0.5 degrees lower than       
the actual angles.                                                            
                                                                              
2.2  VICAR2 Labels of Browse Images                                           
                                                                              
    The browse versions of MIDR's were created by reducing the original       
7168 by 8192 MIDR by a factor of 8.  The VICAR2 labels for the browse         
images do not accurately reflect the size reduction, in that parameters       
PROJSAMP, PIXSIZ, and SPECLINE still pertain to the original MIDR size.       
                                                                              
2.3  Data Feathering                                                          
                                                                              
    MIDR products on the CD-ROM's, in some cases, have had a feathering       
algorithm applied to suppress banding due to BIDR differences.  The file      
CONTENTS.TAB includes a column (column no. 31) that specifies whether         
or not feathering has been applied.  A "C" in this column indicates           
correction by feathering, while an "R" means not feathered.                   
                                                                              
3.  Comments on volume MG_0001, version 2                                     
                                                                              
3.1  Difference between MG_0001 file structure and Standard file structure    
                                                                              
    The files MCUMDIR and CONTENTS are in the root directory of MG_0001.      
They are in subdirectory INDEX of MG_0002 and subsequent CD's.  In addition,  
MG_0001 has a label file PMIDRDS.LBL in the LABEL directory.  This file       
is replaced by NPMIDRDS.LBL and SPMIDRDS.LBL in the LABEL subdirectory        
of MG_0002 and subsequent CD's.  For MG_0002 and subsequent CD's, a number    
of other label and text files (including AAREADME.TXT) have been updated to   
reflect these and a few other minor changes.                                  
                                                                              
3.2  Difference between Standard and Engineering F-MIDR's                     
                                                                              
    The ten F-MIDR's on this CD-ROM are not standard products; rather,        
they are engineering test products generated before delivery of               
operational software.  There are three primary differences between            
Engineering F-MIDR's and standard F-MIDR's.  First, Engineering F-MIDR's      
consist of 20 orbits whereas standard F-MIDR's contain 24 orbits.             
Second, Engineering F-MIDR's are not necessarily complete on the trailing     
edge and may contain missing orbits within the body of the mosaic that        
have since been processed.  The gap at the trailing edge of some of the       
F-MIDR's is a start of mapping gap and is present because processing          
began with orbit 376.  Gaps in the bodies of the F-MIDR's are present         
because the Image Data Processing Team (IDPT) was instructed not to wait      
until all orbits had completed the processing queue.  Therefore, orbits       
that the SAR Data Processing Team (SDPT) had trouble processing appear        
as gaps in the Engineering F-MIDR's even though the orbit has now been        
processed.                                                                    
                                                                              
3.3  Error in VICAR2 Keyword PROJSAMP                                         
                                                                              
    This CD-ROM has an error in the VICAR2 labels for the mosaicked           
framelets.  Specifically, the value for PROJSAMP does not vary from           
framelet to framelet.                                                         
                                                                              
3.4  VICAR2 Labels of MIDR Framelets                                          
                                                                              
    Some of the MIDR framelet files have a VICAR2 label embedded at the       
end of the file, in addition to the normal VICAR2 label at the beginning      
of the file.  This extra label is not documented in the PDS detached label.

    In two of the data subdirectories, the product ID given in the            
VICAR2 embedded labels is not correct.  Specifically, the VICAR2 label        
has an N for north latitude instead of an S for south latitude.  The          
correct IDs are as follows:

    The PDS label files for the browse images on this CD-ROM (all named       
BROWSE.LBL) contain incorrect entries in the IMAGE object.  The keyword

engineering test product F-MIDRD's on MG_0001.                                
                                                                              
5.  Comments on GEO.LBL for Volumes MG_0001 to MG_0022                        
                                                                              
    The PDS label file GEO.LBL on Magellan CD's volumes 1 to 22 contain       
incorrect DESCRIPTION keyword entries for the objects MINIMUM_LONGITUDE

    Framelet 56 for C1-MIDR 60N014 has zeros in approximately 6.5 records

    The file CONTENTS.TAB, in directory INDEX, shows 141 as the maximum       
longitude for product C1_75N119.  The maximum longitude entry for this        
product should be 186.

    The VICAR labels for all image files (*.IMG) in the directory F45N241     
incorrectly list this product as being 'F-MIDR.45N241;1'.  This product is    
actually 'F-MIDR.45N241;2', i.e. version 2.  The detached PDS labels in       
this directory are correct.

    The file FRAME.TAB in directory C175N209 incorrectly reports the maximum  
longitude of framelet C1F02 to be 175.9575.  This should be 183.4368.  Also,  
FRAME.TAB reports the minimum longitude of framelet C1F03 to be 183.4495.     
The minimum longitude for framelet C1F03 is 175.9738.  (Although locations    
are reported to four significant figures, spatial accuracy is actually much   
lower.)

    The file CONTENTS.TAB, in subdirectory INDEX, reports the maximum         
latitude (northernmost), the minimum latitude (southernmost), the maximum     
longitude (easternmost) and the minimum longitude (westernmost).  Since the   
product C2-MIDR 60N033 on this CD lies in the far northern hemisphere, the    
image wraps around itself.  Consequently, the maximum longitude and minimum   
longitude entries in CONTENTS.TAB are not appropriate indications of the      
longitude limits for this image.  These entries in CONTENTS.TAB have          
therefore been set to 0. This approach adheres to the file structure given    
in the MIDRCD SIS.  Note that the top edge of this product extends for 401    
degrees, from 192.1 degrees, through 360 degrees and continuing to 233.2      
degrees.

     The following information, concerning the definitions of some PDS        
keywords, should be added to the DATA_SET_MAP_PROJECT_CATALOG descriptions    
contained in [LABEL]DSMAP*.LBL files.                                         
                                                                              
    NOTE: The PDS keywords whose names begin 'X_' and 'Y_', e.g.              
    X_AXIS_PROJECTION_OFFSET, Y_AXIS_PROJECTION_OFFSET, etc.,  use 'X'        
    to denote LINE and 'Y' to denote SAMPLE. This is reversed relative        
    to the definitions in Snyder (1987), i.e. x(Snyder) = y(PDS), and         
    y(Snyder) = -x(PDS).

    The C2 MIDR's C260N333, C260N153 and C260N093 on this CD lie far enough   
north so that the top boundaries of these products actually wrap around       
themselves.  Consequently, the entries in [INDEX]CONTENTS.TAB, maximum        
longitude (easternmost) and minimum longitude (westernmost), for these        
products are not an appropriate indication of the limits of these products.   
These entries have therefore been set to 0.  Latitude and longitude limits    
for these products can be obtained from the VICAR label or from the file      
FRAME.TAB.

17. Comments on "PRODUCT_ID" for Volumes MG_0053 and Above                    
                                                                              
    With the advent of cycle 2 data on volume MG_0053, it was decided         
to alter the format and meaning of PRODUCT_ID version numbers (note that      
the version number follows the ";" in the PRODUCT_ID).                        
    If the PRODUCT_ID has a single digit version number (e.g.                 
F-MIDR.25N333;1), the product is a cycle 1 product.  In this case, a          
higher version number means an improved version of the same product.          
    If the PRODUCT_ID has a three digit version number (e.g.                  
F-MIDR.15S049;201), the version number format is :                            
                     product_name;cvv                                         
where                                                                         
                  c   is the cycle number                                     
                  vv  is a "version" number.                                  
However, in this case the version number does NOT necessarily refer           
to an improved version of the same product.  It may mean that this            
is a completely different type of MIDR product at this latitude and           
longitude.  For example, F-MIDR.nnzmmm;202 may be a right looking             
image while F-MIDR.nnzmmm;201 is a left looking one.  The file                
[INDEX]CONTENTS.TAB will provide this information.                            
                                                                              
18. Comments on GEOM.TAB for MG_0001 to MG_0052                               
                                                                              
    The file GEOM.TAB in each product sub-directory contains geometry         
information such as orbit number, boresight longitude and latitude, etc.      
The orbit numbers referenced in these files on CD's 1 to 52 are               
incorrect.  The table entry for orbit number was 3 bytes long when it         
should have been 4 bytes.  Cycle 1 and cycle 2 orbit numbers were also        
intermixed.  These files should not be used.  The problem has been fixed

files will be available on a future CD.                                       
                                                                              
19. Comments on GEO.TAB for MG_0001 to MG_0052                                
                                                                              
    The file GEO.TAB, contained in the top level directory, reports           
the positions and types of Venus features.  Up to and including CD 52         
this file has included the names of provisional features.  Starting           
with CD 53, GEO.TAB includes only the names of IAU (International             
Astronomical Union) approved features.

20.1 [INDEX]CONTENTS.TAB Values                                               
                                                                              
    The C2 MIDR's C260N213, C260S213, C260S153, C260S093, C260S033 and        
C260S273 on this CD lie far enough north (or south) so that the top           
(or bottom) boundaries of these products wrap around themselves.              
Consequently, the entries in [INDEX]CONTENTS.TAB, maximum longitude           
(easternmost) and minimum longitude (westernmost), for these products         
are not an appropriate indication of the limits of these products.            
These entries have therefore been set to 0.  Latitude and longitude limits    
for these products can be obtained from the VICAR label or from the file      
FRAME.TAB.

20.2 VICAR Label Keywords for Product C160N347                                
                                                                              
    VICAR labels in Magellan image files contain a keyword "IMAGE".  This     
keyword is supposed to have the value "NORMALIZED RADAR CROSS SECTION".       
The VICAR keyword "IMAGE" in all image files (*.IMG) for the product          
C160N347 on volume MG_0054, contains the incorrect value "RADAR CROSS         
SECTION POWER".

     The PDS label file [INDEX]MCUMDIR.LBL is missing a line (the             
fifth record) containing the ^TABLE value.  The fifth record of this          
file should be:

     The keyword "PRODUCT", in the VICAR labels for the files                 
BROWSE.IMG and C1F*.IMG, incorrectly list this product as being               
'C1-MIDR.00N060;201'.  The product in this directory is                       
'C1-MIDR.00N060;202'.  This is a cycle 2 product with a "right"               
look direction.  The product in directory C100N060 of volume MG_0057 is       
the 201 ("left" look direction) version of C100N060.  Since the VICAR         
labels were incorrect, the  "IMAGE_ID" keyword in the following files         
also incorrectly refer to this product as 'C1-MIDR.00N060;201':               
     [INDEX]CONTENTS.TAB

This product, 'C1-MIDR.00N060;202', is correctly referred to by the

themselves.  Consequently, the entries in [INDEX]CONTENTS.TAB, maximum        
longitude (easternmost) and minimum longitude (westernmost), for these        
products are not an appropriate indication of the limits of these

     This file has the wrong record format.  It is a variable length

     The fifth record, which contains the entry for ^TABLE, is missing        
the carriage return character (ASCII 13) in the 79th byte and the             
line feed character (ASCII 10) in the 80th byte.  This may cause a problem    
for automated procedures which use this file.

     The file [INDEX]MCUMDIR.TAB on these CD's is an exact duplicate of       
the MCUMDIR.TAB file on CD 63.  The file was not updated for new entries      
and contains the repeated entries reported in section 22.2.                   
                                                                              
25. Comments Concerning VMS Record Attributes of IMAGE Files on All Volumes   
                                                                              
     Image files (*.IMG) and HIST.TAB files for all products on MIDR CD's     
use a "print file carriage control" record attribute instead of a  null       
"carriage control" record attribute.  This will cause a problem when using    
the COPY command in VMS.  In general there is no reason to COPY these files,  
as applications such as TAE or the standard FORTRAN library can access the    
files without any difficulty.                                                 
     The files can be copied, if necessary, using the VMS utility "CONVERT".  
Use any editor to produce a file called MIDR.FDL, which should contain the    
following lines:

where: cddev       is the VMS device name for the CD reader,                  
       directory1  is the directory name containing the image file to be      
                   converted,                                                 
       directory2  is the name of the directory where the converted file      
                   is to be placed,                                           
       disk        is the VMS device name for your hard disk,

    Starting with MG_0068 the description of C3-MIDRD's in                    
[LABEL]C3MIDRDS.LBL has been changed to more accurately read:                 
"One C3-MIDR frame covers 137.5 degrees in latitude and 157 degrees in        
 longitude, at the equator."                                                  
instead of:                                                                   
"One C3-MIDR frame covers 80 degrees in latitude and 120 degrees in           
 longitude.  No C3-MIDRs were generated during the first mapping cycle."

27.1 [INDEX]CONTENTS.TAB Values                                               
                                                                              
    The C2 MIDR C260S333 lies far enough south so that the bottom boundary    
of this product wraps around itself.  The C3 MIDR C314N180 also wraps around  
itself due to the extreme scale of C3 MIDR's.  Consequently, the entries in   
[INDEX]CONTENTS.TAB, maximum longitude (easternmost) and minimum longitude    
(westernmost), for these products are not an appropriate indication of the    
limits of these products.  The entries for maximum longitude and minimum      
longitude in the file [INDEX]CONTENTS.TAB have therefore been set to 0.       
In some cases, for C3 MIDR's, an individual framelet has a longitude extent   
of more than 360 degrees.  The maximum and minimum longitude entries in       
FRAME.TAB have also been set to 0 when this occurs.  The latitude and         
longitude extents of these frames can be found from the VICAR label for       
each framelet.                                                                
                                                                              
  C260S333   the bottom edge of this product extends for 401 degrees, from

     Note that individual framelets for the product C314N180, also wrap       
around themselves.  Thus maximum and minimum longitude entries for some       
framelets in the file [C314N180]FRAME.TAB have been set to 0.  Latitude       
and longitude limits for these products can be obtained from the VICAR        
label.

    The detached PDS label files for framelets C3F01, C3F02, C3F07            
and C1F08 should  have had the values of keywords MAXIMUM_LONGITUDE           
and MINIMUM_LONGITUDE set to 0.  Latitude and longitude product limits        
in the detached PDS label files should conform to those in the file           
FRAME.TAB.  This was not done for this product.

    Due to the extreme scale of C3 MIDR's the top edge (in the case of        
northern products) or the bottom edge (in the case of southern products)      
wraps around itself.  Consequently, the entries in [INDEX]CONTENTS.TAB,       
maximum longitude (easternmost) and minimum longitude (westernmost), are      
not an appropriate indication of the limits of these products.  The           
entries for maximum longitude and minimum longitude in [INDEX]CONTENTS.TAB    
have therefore been set to 0.  In some cases, an individual framelet has      
a longitude extent of more than 360 degrees.  The maximum and minimum         
longitude entries in FRAME.TAB have also been set to 0 when this occurs.      
The latitude and longitude extents for these frames can be found from         
the VICAR label for each framelet.

    The C2 MIDR C260N333 on this CD lies far enough north so that the         
top boundary of this product wraps around itself.  Consequently, the          
entries in [INDEX]CONTENTS.TAB, maximum longitude (easternmost) and           
minimum longitude (westernmost) are not an appropriate indication of the      
limits of this product.  These entries have therefore been set to 0.          
Latitude and longitude limits can be obtained from the VICAR label or         
from the file FRAME.TAB.  The actual limits are:
