csspck2spk

The CASSINI mission requires that specific PCK SPICE files be matched to each SPK SPICE file. This program will do the matching. The reference table used for the matching is generated by JPL, generally on a monthly basis, and is located at https://cassini.jpl.nasa.gov/io/spice/pcktospk_mapping.htm. Each time this table is updated, it should be downloaded and converted from html to a text table (using your favorite converter, maybe lynx), and then named pck2spk_????.map. The "Last Updated..." line and title header should be saved and commented out with the "#" character, and each PCK/SPK pair should occupy one line with a comma delimeter. Do not leave blank lines. When you are done, mv the file to the $ISIS3DATA/cassini/kernels/pck directory. The file should look something like this:

            # Last Updated: 27-August-2006
            # PCK to SPK File Compatibility Table
            #
            cpck11Aug2006.tpc,060810R_SCPSE_06162_06193
            cpck20Jul2006.tpc,060719R_SCPSE_06130_06162
            cpck14Jun2006.tpc,060614R_SCPSE_06099_06130
    

Next, update the SPK directory with new position files, and the PCK directory with the new ehemeris files. Then run makedb to generate a db file located in the SPK directory and a db file located in the PCK directory.
