• arc (structured array) – Observation arc containing time, rStation_GCRF, and vStation_GCRF fields. May include satID to determine scalar or array-like arc handling.

• kwargs (dict, optional) – Additional keyword arguments passed to ssapy.compute.radec().

Returns:

Tuple containing rr, dd, zz, pmrr, pmdd, dzzdt, and nwrap arrays.
