This is my copy of the US Naval Observatory's NOVAS-C software (https://aa.usno.navy.mil/software/novasc_intro) with a couple bug fixes applied. I've also enhanced it with the ability to open many more versions of the JPL ephemerides. Please give the USNO proper credit if you use this software.
Original Naval observatory code only allows you to access ephemerides DE200, DE403, DE404, DE405, DE406 & DE 421. Access to newer versions of the JPL ephemerides needs to be added.
