VizieR Online Data Catalog: CLASS survey of radio sources (Myers+, 2003)

The data in this table were assembled from pointings at 16503 radio sources in the JVAS and CLASS surveys between 1990 and 1999 using the VLA in A-configuration at 8.4GHz. The resolution is approximately 220 milliarcsec. The data were mapped using an automatic DIFMAP script (Shepherd et al., 1997, ASP Conference Series, 125, 77) which located the brightest radio source within a 2' by 2' box around the pointing position, and searched for all subsidiary components within a 70"x70" box around the brightest source. Sources were regarded as not detected if no component of 5mJy or more was visible in the initial search box. Except in cases of bad data or complicated sources, the positions of primary sources of 30mJy or above are accurate to about 40mas. More details of the process are given in the paper (2003MNRAS.341....1M)
