It contains 473 hot subdwarf candidates obtained after a photometric and astrometric search in 11663 sq. deg. using GALEX, SDSS SuperCosmos and 2MASS. 86 of these candidates were spectroscopically classified following the classification criteria/scheme in Drilling et al (2013). New potentially binary systems have also been flagged.
A detailed information on the identification and characterization of the hot subdwarfs included in this archive can be found at Pérez-Fernández et al. (2015, in prep.)
The SVO hot subdwarf Data Access Service is the result of a collaboration agreement between the Centro de Astrobiología (CAB, INTA-CSIC) and the Universidade de Vigo. It has been developed in the framework of the Spanish Virtual Observatory project supported by the Spanish MINECO through grant AYA 2011-14052. The system is maintained by the Data Archive Unit of the CAB (CSIC -INTA).
