Data Provider/P.I. Chiara Spiniello
Data Collection VEXAS
Data Release DR2

Description This table contains the objects from the VEXAS-AllWISE catalogue that have a counterpart in the DES DR Y1 (matching radius of 3"). The objects are classified via an ensemble of machine leaning algorithm into stars, galaxies and quasars. Optical photometry in grizY bands is given (AB), NIR photometry can be obtained by cross-matching this table with the VEXAS-AllWISE.
Please refer to the full data release description for further information.
