Import HRSC image
This program imports Mars Express HRSC files. This works by first determining whether or not the input file has prefix data. If there is prefix data, the prefix data is collected and used to look for "gaps" - HRSC files can give us a time and exposure duration for each line, we look for where the time + exposure duration =/= next line's time. We populate a table (LineScanTimes) with the prefix data and lineInFile with whether or not a gap should be inserted. For all files, we now process the data and if there were gaps, they will be put in their proper places. This is a two-pass system for files with prefix data, one-pass for files without. The Isis2 equivalent to this program is mex2isis.pl. It is worth noting that regardless of the input file's byte order, the prefix data byte order is always LSB.
Related Applications to Previous Versions of ISISThis program replaces the following applications existing in previous versions of ISIS:
Use this parameter to select the PDS filename. This file must contain the PDS labels, however the image data can be detached and will be automatically obtained from the PDS image pointer keyword. If the pointer is incorrect then use the IMAGE parameter to specify the file containing the binary image data.
Use this parameter to select the output filename
