X-ray surveys provide one of the most efficient ways of selecting AGN. Description: The Table contains the SwiftFT catalog of the serendipitous sources detected in over 370 Swift-XRT fields centered on gamma ray bursts, which were detected between 2004 and 2008 and observed with total exposures ranging from 10ks to over 1Ms. File Summary:
