vo@astron.nlHI lineradioThis service queries the continuum catalogue based on the first data release of Apertif continuum images at a central frequency 1355 MHz, with a bandwidth of ~150 MHz and angular resolution of up to 10''. The catalogue contains 249672 radio sources, many of which have been detected for the first time at these frequencies. Source extraction methods are described in Kutkin et al. 2022. A companion VO table contains the continuum images corresponding to this catalogue (see https://vo.astron.nl/apertif_dr1/q/apertif_dr1_continuum_images/form).2022A&A...667A..38Ahttps://vo.astron.nl/apertif_dr1/q/apertif_dr1_catalogue/infoSurveyResearchserved-byThe VO @ ASTRON TAP serviceLicensed under CC-BYhttps://vo.astron.nl/apertif_dr1/q/apertif_dr1_catalogue/scs.xml?GETapplication/x-votable+xmlRARight Ascension (ICRS decimal)degpos.eq.rarealDECDeclination (ICRS decimal)degpos.eq.decrealSRSearch radiusdegrealRESPONSEFORMATFile format requested for output.meta.code.mimecharMAXRECMaximum number of records returned.
