MROM_1191 and MROM_1192:

Images in the orbit range 64105-64157 were affected by an
SSR read failure at 3/30/2020 13:52:04 SCET UT.  MARCI was
power-cycled on 4/3/2020 (off at 16:37 SCET, on at 18:12)
to reset the hard partition back to empty.

MROM_0968 through MROM_0992:

These 25 volumes contain improved or never-before-archived
images acquired from September 2006 to February 2015.  The
never-before-archived images are:

In April 2019, the PDS Imaging Node sent us a new cumindex.tab
with changes to reflect their moving of the improved MARCI EDRs
from these volumes to their original volumes, replacing the
original EDRs and index.tab information.  Volumes in the range
above now contain only the never-before-archived images.

In that process, some whitespace in some RATIONALE_DESC was
removed from the index.tab and cumindex.tab, so it no longer
matches the RATIONALE_DESC in the EDR header; for example,
B22_018361_1102_MA_00N276W is 'global map swath        (dark
calibration)' in the EDR header but 'global map swath (dark
calibration)' in the tab files.  This applies to many 'dark'
and 'nightside' EDRs, not just those that were originally on
these volumes.

MROM_0638 and MROM_0639:

Images D21_035406_0897_MA_00N312W.IMG,
D21_035407_0897_MA_00N339W.IMG, D21_035448_0911_MA_00N019W.IMG,
D21_035449_0911_MA_00N046W.IMG, and
D21_035450_0912_MA_00N073W.IMG were affected by what was
likely a single-event upset.  MARCI was commanded to reboot
at 02/20/2014 00:41:24 SCET UT.

MROM_0619:

Beginning with orbit 34581, images were affected by what was
likely a single-event upset.  Additionally, images in the
orbit range 34585-34603 were affected by an SSR read failure
at 12/12/2013 09:27:25 SCET UT.  MARCI was power-cycled on
12/13/2013 (off at 20:51 SCET, on at 22:55) to reset the
hard partition back to empty.

MROM_0613:

Images in the orbit range 34200-34219 were affected by what was
likely a single-event upset.  MARCI was commanded to reboot
at 11/13/2013 22:04:40 SCET UT.

MROM_0367:

Images G02_019003_1337_MA_00N330W.IMG and
G02_019004_1337_MA_00N358W.IMG were affected by what was likely
a single-event upset in the MARCI DSP code.  MARCI was
commanded to reboot at 8/16/2010 20:00:00 SCET UT in order to
reload the code.

MROM_0317 through MROM_0325:

Images B19_016884_0593_MA_00N078W.IMG through
B19_017190_0697_MA_00N152W.IMG were affected by what was likely
a single-event upset in the MARCI DSP changing a value in the
companding table; pixels with dn=203 are scattered throughout
those images.  MARCI was commanded to reboot at 3/27/2010
23:53:44 SCET UT in order to reload the companding table.

MROM_0226:

Images B03_010688_1533_MA_00N121W.IMG through
B03_010721_1546_MA_00N302W.IMG were affected by what was likely
a single-event upset in the MARCI DSP changing a value in the
companding table; bright (dn=174) pixels are scattered throughout
those images.  MARCI was commanded to reboot at 11/8/2008
22:17:17 SCET UT in order to reload the companding table.

MROM_0076:

MARCI was powered off at approximately 13:52 on 2007-07-20, during
acquisition of frame 985 of image 4A_05_101480FA00
(P09_004596_2801_MA_00N107W.IMG and P09_004596_2801_MU_00N107W.IMG).
Data from frame 984 are repeated in frames 985-1322 of those two IMGs.

MROM_0001:

The images acquired in mission phase CRUISE are not of Mars and were
not acquired from orbit (MRO had not yet arrived at Mars), so some
of the values (e.g., orbit number, solar distance) in the index.tab
file are not meaningful.

General:

Some MARCI product names have a latitude and longitude specification
other than the '00N'BBB'W' described in the MARCI EDR SIS.  For
these images, the sub-spacecraft (for off-planet images) or center
(for images of Mars) latitude and longitude were used in the name
either because it was not possible to calculate an equator-crossing
longitude or because such a calculation would have resulted in
duplicate product names.  For example, images on the stray light
calibration orbit 1762 (volume MROM_0013) are named with '27S134W',
'58N146W', and '71N317W'.

The MARCI planning periods are represented in image product
filenames by the mission phase descriptor, as noted in the
MARCI SIS.  The planning periods are:

CRU  Cruise instrument check-out/calibration (August 2005)
MOI  post-Mars Orbit Insertion instrument check-out (March 2006)
T0n  Transition to Primary Mission (September-November 2006)
Pnn  Primary Mission (November 2006 - August 2008)
Bnn  Primary and Extended Mission (September 2008 to June 2010)
Gnn  Extended Mission (July 2010 to present)

where n is a digit from 0 to 9.

MRO's Extended Mission starts on 20 December 2008 and ends on
31 December 2010.  MARCI planning periods for Primary Mission and
beyond, however, are defined by Mars year and Earth month; the
letter represents Mars year, and the number represents Earth
month within that Mars year.

The planning period naming scheme was developed to be consistent
with that of the Mars Global Surveyor (MGS) Mars Orbiter Camera
(MOC) dataset to simplify comparisons of data across several Mars
years.  The solar longitude ('L sub s') range of a given numbered
Earth month is roughly the same across the two datasets; for
example, MGS MOC periods M12, E12, R12, and S12 correspond to
MRO MARCI periods P12 and B12.  The letter B represents beta, the
second Mars year of MARCI imaging; G represents gamma, the third
year.
