cds-question@unistra.frgalaxy-clustersradio-galaxiesThe radiosource catalogs have been extracted from 31 NRAO VLA Sky Survey maps (NVSS, Condon et al., 1988AJ....115.1693C) over approximately 550 square degrees of sky in the region of the South Galactic Pole. File table1.dat contains the catalog of 13340 pointlike sources. For each source are given: Right Ascension and Declination, source name (if applicable), peak flux, flux rms from the fit, error on source position as estimated by the fitting algorithm, x and y pixel of the position where the peak has been detected on the map (starting position for the fit), control flags coming from the extraction algorithm, and name of the radio map where the source has been detected. The name is specified for (1) pointlike sources that are detected in a multiple system (name = DSnnnn or TSnnnn) (2) sources initially classified as components of a double system, which has been considered spurious on the basis of the distance between components (name = Cnnnn or DCnnnn). File table2.dat contains the catalog of 2662 double radiosources. For each source the following parameters are given both for the barycentre and the two components: Right Ascension and Declination, source name, peak flux, flux rms from the fit, error on source position as estimated by the fitting algorithm, distance between the components of the double system, x and y pixel of the position where the peak has been detected on the map (starting position for the fit), control flags coming from the extraction algorithm, and name of the radio map where the source has been detected.2001A&A...379...21Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/379/21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/379/35 : Radio-optically selected galaxy clusters II.
