get_gaia_sources

simsit.photometry.get_gaia_sources(ra_deg, dec_deg, radius_deg, gaia_data_release=3, star_lim=-1)

Query Gaia sources within a circular sky region.

Parameters

ra_degfloat

Right ascension in degrees in the ICRS.

dec_degfloat

Declination in degrees in the ICRS.

radius_degfloat

Search radius in degrees.

gaia_data_releaseint, optional

Gaia data release to query, typically 2 or 3.

star_limint, optional

Maximum number of returned sources. Use -1 for no explicit row limit.

Returns

astropy.table.Table

Query results from the Gaia archive.

Notes

This function performs a remote query through astroquery.gaia and therefore requires network access.
