                   CALIB Directory Contents

The CALIB directory contains files useful to compare Regional Targeted 
Mosaic (RTM) 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 RTMs.

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

Bandpasses for each WAC filter and for the NAC are given in tables having 
the nomenclature:

  MDISBPWa.TAB where:

   a = A through M for different filters:
