cds-question@unistra.frradio-continuum-emissionredshiftedsurveysactive-galactic-nucleiWe present the catalog of the KVN Calibrator Survey (KVNCS). This first part of the KVNCS is a single-dish radio survey simultaneously conducted at 22 (K band) and 43GHz (Q band) using the Korean VLBI Network (KVN) from 2009 to 2011. A total of 2045 sources are selected from the VLBA Calibrator Survey with an extrapolated flux density limit of 100mJy at the K band. The KVNCS contains 1533 sources in the K band with a flux density limit of 70mJy and 553 sources in the Q band with a flux density limit of 120mJy; it covers the whole sky down to -32.5{deg} in decl. We detected 513 sources simultaneously in the K and Q bands; ~76% of them are flat-spectrum sources (-0.5<={alpha}<=0.5). From the flux-flux relationship, we anticipated that most of the radiation of many of the sources comes from the compact components. The sources listed in the KVNCS therefore are strong candidates for high-frequency VLBI calibrators.2017ApJS..228...22Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/228/22CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/323 : International Celestial Reference Frame 2, ICRF2 (Ma+, 2009)I/251 : VLBI International Celestial Reference Frame (ICRF) (Ma+, 1997)J/MNRAS/426/2107 : KNoWS pilot bright sample (Righini+, 2012)J/AJ/143/35 : KCAL VERA 22 GHz calibrator survey (Petrov+, 2012)J/MNRAS/419/1097 : The EVN Galactic Plane Survey - EGaPS (Petrov, 2012)J/AJ/142/35 : The VLBA Galactic Plane Survey (VGaPS) (Petrov+, 2011)J/A+A/526/A102 : VLBI imaging of extragalactic radio sources (Bourda+, 2011)J/A+A/520/A113 : VLBI detection of extragalactic radio sources (Bourda+, 2010)J/AJ/139/1713 : Celestial Reference Frame at 24 and 43GHz.
