Full details on the Orbit Determination (OD) Code and Report to come later this week, but the beginning is always a good place to start. Here is the required format for your OD input file.
The input file should contain one line for every possibly usable night with the following info:
- UT date/time at middle of observation (yyyy mm dd hh:mm:ss)
- RA (hh mm ss.ss)
- Dec (dd mm ss.s)
- solar vector in x,y,z format, given to precision reported by JPL Horizons
- earth velocity vector in x,y,z format, given to precision reported by JPL Horizons
