get_ephemeris_time_from_epoch

pride.utils.get_ephemeris_time_from_epoch(epoch: astropy.time.Time) → numpy.ndarray

Calculate ephemeris time from epoch

Ephemeris time is the number of TDB seconds since J2000. This function converts an epoch to ET by converting it to TDB using Astropy, calculating the difference from J2000.tdb, and converting the difference to seconds, also using Astropy.

Para epoch:

Epoch or sequence of epochs as astropy.time.Time object

Returns:

Ephemeris time as numpy array
