get_radec_catalog¶
- grizli.catalog.get_radec_catalog(ra=0.0, dec=0.0, radius=3.0, product='cat', verbose=True, reference_catalogs=['GAIA', 'LS_DR9', 'PS1', 'Hubble', 'NSC', 'SDSS', 'WISE', 'DES'], use_self_catalog=False, **kwargs)[source]¶
Decide what reference astrometric catalog to use
First search SDSS, then WISE looking for nearby matches.
- Parameters
- ra, decfloat
Center of the query region, decimal degrees
- radiusfloat
Radius of the query, in arcmin
- productstr
Basename of the drizzled product. If a locally-created catalog with filename that startswith
productis found, use that one instead of the external (low precision) catalogs so that you’re matching HST-to-HST astrometry.- reference_catalogslist
Order in which to query reference catalogs. Options are ‘GAIA’, ‘PS1’ (STScI PanSTARRS), ‘SDSS’, ‘WISE’, ‘NSC’ (NOAO Source Catalog), ‘DES’ (Dark Energy Survey DR1), ‘Hubble’ (Hubble Source Catalog v3), ‘LS_DR9’, ‘LS_DR10’ (LegacySurveys DR9, DR10).
- Returns
- radecstr
Filename of the RA/Dec list derived from the parent catalog
- ref_catalogstr, {‘SDSS’, ‘WISE’, ‘VISIT’}
Provenance of the
radeclist.
