The EVN Galactic Plane Survey - EGaPS

Abstract

I present a catalogue of positions and correlated flux densities of 109 compact extragalactic radio sources in the Galactic plane determined from analysis of a 48 hour VLBI experiment at 22 GHz with the European VLBI Network. The median position uncertainty is 9 mas. The correlated flux densities of detected sources are in the range of 20 to 300 mJy. In addition to target sources, nine water masers have been detected, two of them new. I derived position of masers with accuracies 30 to 200 mas and determined velocities of maser components and their correlated flux densities. The catalogue and supporting material is available at http://astrogeo.org/egaps.
