cr_calib.txt Info file for the CALIB/ directory of that volume.
Any calibration files obtained as part of data
collection for this data set may be found in the
data/ directory. Calibration observations will
have sequence numbers that force them to the end
of directory listings. That is, if observations
have sequence numbers in the 1000 range, calibrations
will likely have numbers in the 9000 range.
cr_ephem.txt Info file for what was then called the EPHEM/ directory.
The ephemeris file is located in the GEOMETRY/ directory
of the present data set.
cr_index.txt Info file for the original INDEX/ directory. The
indices described may also be found in the INDEX/
