The Cosmic Lens All-Sky Survey (CLASS) is an international collaborative program aimed at obtaining high-resolution radio images of over 10000 flat-spectrum radio sources in order to create the largest and best studied statistical sample of radio-loud gravitationally lensed systems. CLASS is aimed at identifying lenses where multiple images are formed from compact flat-spectrum radio sources, which should be easily identifiable in the radio maps (Browne et al., 2003MNRAS.341...13B). In four observing ``seasons'' from 1994-1999, CLASS has observed 13832 radio sources. When combined with the JVAS survey, the CLASS sample contains over 16,000 images. Using the GB6 and NVSS surveys, a complete statistical subset of 11685 sources has been constructed. These were selected from the NVSS 20-cm (Condon et al., 1998, Cat. <VIII/65>) and GB6 6-cm (Gregory et al., 1996, Cat. <VIII/40>) catalogues by the selection criteria: declination >0deg, |b|<10deg, S(6cm)>=30mJy, and spectral index between 6 and 20cm flatter than -0.5 (S proportional to frequency^+alpha^). The remaining sources were selected using earlier versions of these catalogues or with slightly relaxed versions of these criteria. Introduction: 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)
