摘要：
The Cosmic Lens All-Sky Survey (CLASS) is aimed at identifying lenses where multiple images are formed from compact flat-spectrum radio sources. In four observing "seasons" with the VLA A-array at 8.45 GHz in 1994, 1995, 1998 and 1999, CLASS has observed over 12,000 radio sources. When combined with the JVAS survey, the CLASS sample contains over 15,000 images and at least 17 lenses, with 11 so far in CLASS as well as a number of candidates still being followed up. In this poster, we present a summary of the CLASS observations, the JVAS-CLASS sample, and statistics on subsamples of the survey.
