Table information for 'whsp.main'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: The catalog 1WHSP is the result of a multi-frequency selection for blazars like SED, further filtered using IR-radio and IR-X-ray flux-ratios. The sample assembled contains almost 992 sources of HSP blazars, of which 425 are previously known blazars, 151 new identifications and 416 blazar candidates. On the very high energy trend, 299 are confirmed GeV gamma-ray photons emitters and 36 have already been detected in the TeV band.

For a list of all services and tables belonging to this table's resource, see Information on resource 'WISE High Synchroton Peak blazar candidates catalog'
