Functions

func GetCMSystem

func GetCMSystem(object_names []string, now time.Time) (system cmech.CMSystem)

get a system of celestial objects from the JPL Horizons server

func GetSV

func GetSV(oname string, horizons_time time.Time) cmech.Body

get state vector for a named celestial body return a cmech.Body convert to units of km, sec, kg takes horizons_time time.Time allowing multiple objects to use the same starting time TODO, pass a slice object names to query using the same connection
