empyrean.EphemerisResult

class EphemerisResult(ephemeris, sensitivity=None)

Bases: object

Result of empyrean.generate_ephemeris().

Parameters:

• ephemeris (Ephemeris)

• sensitivity (ObservationSensitivities | None)

ephemeris

Predicted astrometry table (one row per orbit × observer × epoch) with topocentric coordinates and observation covariance.

Type:

Ephemeris

sensitivity

Flat per-(orbit_id, obs_code, epoch) sensitivity table — observation Jacobians + optional Hessians. None when no input covariance was supplied.

Type:

ObservationSensitivities, optional
