                   CALIB Directory Contents

The CALIB directory contains files useful to compare Multispectral 
Reduced Data Records (MDRs) data with reflectance and spectral data 
from other sources. This is a subset of the full set of calibration 
files and explanatory text that is included with the Experiment Data 
Record (EDR) and Calibrated Data Record (CDR) archives.

CALINFO.TXT      -  The file you are reading. It contains descriptions of
  calibration files relevant to MDRs.


/SUPPORT         - This directory contains characterizations of the
instrument that will be useful for analysis of MDR data.

  Bandpasses for each WAC filter included in MDRs are given in tables 
  having the nomenclature

  MDISBPWa.TAB where:

   a = C through L for different filters:
