data_weight_Veres2017(obsCode, jd_tdb, catalog=None, program=None)[source]

Return data weighting given an observatory, Julian date, and optionally catalog and program. The weighting is based on the work of Veres et al.

See: Veres et al. 20217 https://arxiv.org/pdf/1703.03479

Parameters:

  • obsCode (str) – The observatory code

  • jd_tdb (float) – Julian date in TDB of the observation

  • catalog (str, optional) – The stellar catalog used for measuring the astrometry, by default None

  • program (str, optional) – The program code assigned by the Minor Planet Center, by default None

Returns:

Astrometric uncertainty in arcseconds

Return type:

float
