Galactic to Equatorial coordinates for ISM Spectra (gaiafpr_contrib.ism_gaiagal_to_eq)
The table has 11216 rows, 6 columns.
Description
This table contains a mapping from Gaia's Galactic to equatorial coordinates. The mapping is meant to be used with the GaiaFPR ISM Spectra table and enables IVOA ConeSearch capabilities. The transformation from galactic to equatorial coordinates follows Chapter 4.1.7 from the official documentation of GaiaDR3.
