pint.solar_system_ephemerides.objPosVel
- pint.solar_system_ephemerides.objPosVel(obj1, obj2, t, ephem, path=None, link=None)[source]
Compute the position and velocity for solar system obj2 referenced at obj1.
This function uses astropy solar system Ephemerides module.
- Parameters:
obj1 (str) – The name of reference solar system object
obj2 (str) – The name of target solar system object
tdb (Astropy.time.Time object) – TDB time in Astropy.time.Time object format
ephem (str) – The ephem to for computing solar system object position and velocity
path (str, optional) – Local path to the ephemeris file.
link (str, optional) – Location of path on the internet.
- Returns:
solar system obj1’s position and velocity with respect to obj2 in the J2000 cartesian coordinate.
- Return type:
PosVel object.
