Observations of 44 extragalactic radio sources with the VLBA at 92 cm. A list of potential calibrators and targets for LOFAR and RadioAstron.

RAMPADARATH H., GARRETT M.A. and POLATIDIS A.

Abstract (from CDS):

We have analysed VLBA 92cm archive data of 44 extragalactic sources in order to identify early targets and potential calibrator sources for the LOFAR radio telescope and the RadioAstron space VLBI mission. Some of these sources will also be suitable as ``in-beam'' calibrators, permitting deep, wide-field studies of other faint sources in the same field of view. All publicly available VLBA 92cm data observed between 1 January 2003 to December 31, 2006 have been analysed via an automatic pipeline, implemented within AIPS. The vast majority of the data are unpublished. The sample consists of 44 sources, 34 of which have been detected on at least one VLBA baseline. 30 sources have sufficient data to be successfully imaged. Most of the sources are compact, with a few showing extended structures. Of the 30 sources imaged, 13 are detected on the longest VLBA baselines (∼9Mλ), while all were detected on baselines greater than 2Mλ (the maximum baseline of LOFAR including the current international baselines).
