2007AJ....133.2487P VERA 22 GHz Fringe Search Survey Leonid Petrov, Tomoya Hirota, Mareki Honma, Katsunori M. Shibata, Takaaki Jike, and Hideyuki Kobayashi Abstract. This paper presents results of a survey search for bright compact radio sources at 22 GHz with the VERA radio interferometer. Each source from a list of 2494 objects was observed in one scan for 2 minutes. The purpose of this survey was to find compact extragalactic sources bright enough at 22 GHz to be useful as phase calibrators. Observed sources were either (1) within 6 deg of the Galactic plane, or (2) within 11 deg of the Galactic center, or (3) within 2 deg of known water masers. Among the observed sources, 549 were detected, including 180 extragalactic objects that were not previously observed with the very long baseline interferometry technique. Estimates of the correlated flux densities of the detected sources are presented. It was found that the probability of detecting a 200 mJy source with 120 s of integration time is 60%.
