Second VLBA calibrator survey: VCS2
Listed in IVOA Registry (Virtual Observatory)
This paper presents an extension of the Very Long Baseline Array Calibrator Survey, called VCS2, containing 276 sources.
Description
This survey fills in regions of the sky that were not completely covered by the previous VCS1 calibrator survey. The VCS2 survey includes calibrator sources near the Galactic plane, -30{deg}<DE<-45{deg}, and VLA calibrators.
The positions have been derived from astrometric analysis of the group delays measured at 2.3 and 8.4 GHz using the Goddard Space Flight Center CALC/SOLVE package. From the VLBA snapshot observations, images of the calibrators are available, and each source is given a quality code for anticipated use. The VCS2 catalog is available from the NRAO Web site.
