The Arecibo Legacy Fast ALFA extragalactic HI survey uses the Arecibo multibeam receiver to survey 7000 square degrees of high galactic latitude sky. Utilizing the high sensitivity of Arecibo, the survey will detect over 20000 HI sources in the local universe. The survey products include catalogs with extracted measurements and HI parameters, as well as integrated HI spectral profiles. The survey is currently served by NED.
