Polarisation of 404 radio sources at 6 and 20cm
Listed in IVOA Registry (Virtual Observatory)
Accurate positions of 404 compact radio sources used as calibrators by the VLA are presented.
Description
In addition, the structure and polarization of each source at both 4885 and 1465MHz are given. Eighty-five percent of the sources have spectral indices flatter than 0.5; all of these are dominated by an unresolved core.
Half of these flat-spectrum sources contain nearby, associated diffuse structure at a level exceeding approximately 0.4% of the core brightness at 20cm.
