cds-question@unistra.frbl-lacertae-objectsquasarsradio-sourcesWe discuss the properties of the sources in the CLASS blazar survey, which aims at the selection of low radio power (P_5GHz_<10^25^W/Hz) blazars. We use Very Large Array (VLA) data from available catalogues and from our own observations to constrain the radio core-dominance of the sample which, together with the flat radio spectral index, is a signature of the blazar activity. X-ray data from the ROSAT All Sky Survey were also collected in order to constrain the radio-to-X-ray luminosity ratio of the sources.2004MNRAS.348..937Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/348/937CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/40 : GB6 catalog of radio sources (Gregory+ 1996)J/MNRAS/326/1455 : The CLASS blazar survey.
