hrscsep - Separate MEX HRSC file into individual parts
This program will read prefix bytes from a VICAR-formatted
Mars Express HRSC file. The ephemeris time and exposure
time are both extracted from the prefix bytes and then
written to an ASCII file. The difference between ephemeris
times for consecutive image lines is also written to the
ASCII file to determine where skipped lines exist. These
values can then be accessed by a Perl script. This program
was written primarily to handle the byte-swapping of the
prefix data for Solaris systems. The native format of the
MEX HRSC data is LSB. This program will work on Linux
systems as well.

ADDITIONAL NOTES:

Parm	Description
FROM	Input VICAR-formatted MEX HRSC file
BASENAME	Base name of a multi-sectioned file. If the input file had to be divided into smaller sections to be processed, then each file section must follow the naming convention of input.section#. The "input" portion of the filename is the original name of the file with the extension ".section#" appended. The # signifies an actual number, such as 1, 2, 3, so on that says what order the sections go together.
NSECTION	Number of sections in input file.
FILELIST	Processing list
SKIP	This is the number of bytes to skip to get to the first image line of the FROM file.
NL	This is the number of lines in the FROM file.
NBYTES	This is the number of bytes in each line of the FROM file.
