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.

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