empyrean.StationRaDecConfig

class StationRaDecConfig(sigma_prior_arcsec=0.3, min_obs_per_station=5)

Bases: object

Per-station RA/Dec bias-fit configuration.

Schur-eliminated nuisance parameters that absorb per-station pointing offsets, fit alongside the orbit. Default thresholds target modern survey arcs.

Parameters:

• sigma_prior_arcsec (float)

• min_obs_per_station (int)

sigma_prior_arcsec

1-σ Gaussian prior on the per-station offset, in arcseconds. Default 0.3.

Type:

float

min_obs_per_station

Minimum observations per station required to allocate a bias parameter for that station. Default 5.

Type:

int
