One half of target sources has been detected. The detection limit was around 200mJy. We derived the correlated flux densities of 877 detected sources in three ranges of projected baseline lengths. The objective of these observations was to determine the suitability of given sources as phase calibrators for dual-beam and phase-referencing observations at high frequencies. Preliminary results indicate that the number of compact extragalactic sources at 22GHz brighter than a given correlated flux density level is twice less than at 8GHz.</description><source format="bibcode">2012AJ....143...35P</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/35</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/445/465">J/A+A/445/465 : ACTA 18.5 and 22GHz fluxes of Kuehr 5GHz sample (Ricci+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/133/2487">J/AJ/133/2487 : VERA 22GHz Fringe Search Survey (Petrov+, 2007)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/AJ/142/89">J/AJ/142/89 : VLBA Galactic Plane Survey.
