Note: 'dsn.pl' produces the comm schedule at /proj/rac/ops/ephem/dsn_summary.dat. /pool14/chandra/DSN.schedule is symbolic linked to this. This link is used to create: https://icxc.cfa.harvard.edu/dsop/dsn_summary.dat by https://icxc.harvard.edu/dsop/GTO/essrm9.php which is physically located at: /proj/web-icxc/htdocs/dsop/GTO/essrm9.php. This php script also uses:

FORTRAN Package:

geopack: fortran codes convert Chandra ECI linear coords to GSE, ESE coods. cocochan.f is written by Robrt Cameron. README file for the older version can be found at: /data/mta4/proj/rac/ops/ephem/geopack/README.

wcstools: this is a package of programs and a library of utility subroutines for setting and using the world coordinate systems (WCS) in the headers of the most common astronomical image formats, FITS and IRAF .imh, to relate image pixels to sky coordinates. Please read: http://tdc-www.harvard.edu/software/wcstools/ for more details.
