EGaPS: EVN Galactic Plane Survey -- search for more K-band calibrators using EVN



Text of the proposal in PDF format,   

Objectives of the campaign

A 48 hour observing session with the European VLBI Network at K-band (22 GHz) for observing 369 radio candidate source was run on 2009.10.27—2009.10.29. The goal of the experiment was to increase the number of compact extragalactic radio sources useful as calibrators near the Galactic plane for supporting VERA and VLBA experiments focused on the study of galactic objects. Previous observations with the VLBA in 1994--2009 in S/X produced a list of 4337 sources, with position accuracy better than 5 mas and with S/X images. However, the density of this catalogue is not sufficient to provide enough calibrators closer than 2° near the Galactic plane for VERA and VLBA observations of many interesting galactic objects. VERA observations, in particular, critically depends on availability of calibrators within 2°.2 of a target source.
