OBLATE SPHEROID LATITUDE AND LONGITUDE
Use IDL function
This program assumes the far field approximation. Although I solved the trigonometric relations myself, useful relations for the geometry and coordinate description of an oblate spheroid can be found at NASA's PDS Atmospheres Node.
SCIENCE / COMPUTER REFERENCE DOCUMENTS
MSL AREOCENTRIC LONGITUDE TABLE (msl_LS_table.txt)
This table gives the areocentric longitude (LS, a measure of the season) during the MSL mision. LS values are given at the beginning (midnight) of each sol. Calculations used the IDL routines available at ASU, which follow the methods of Piqueux et al. (2015). To determine the times for each mission sol, I used the landing time given in e.g., Blake et al. (2013), and the duration of Mars sols given in Allison and McEwen (2000). The Mars year numbering follows Clancy et al. (2000).
OUTER PLANET GEOMETRY TABLE (kmdeg.txt)
The Outer Planet Geometry Table (kmdeg.txt) lists several quantities as a function of latitude: planetographic latitude, planetocentric latitude, kilometers per degree latitude and per degree longitude, conversion between east/west meters per second and degrees longitude per day, Coriolis parameter f, planetocentric radius, and latitude circle radius.
File updated 2014 to correct an error and provide km/deg scaling factors in latitude for both planetographic and planetocentric coordinates.
BATCH-FIX TEXT FILESI'm sure there are simpler and slicker ways to convert Mac to Unix line breaks or to search and replace within several text files, but these are super easy once they're installed. Also, they save the original files in case you messed up somehow.
To use these, save them somewhere in your unix path, and chmod a+x them. Perl must be installed (probably already is).
