UVIT DR1, comprehensive catalog of UVIT obs.
Listed in IVOA Registry (Virtual Observatory)
We present the first comprehensive source catalog (UVIT DR1) of ultraviolet (UV) photometry in four far-UV (FUV~1300-1800{AA}) and five near-UV (NUV~2000-3000{AA}) filters of the Ultraviolet Imaging Telescope (UVIT) on board AstroSat.
Description
UVIT DR1 includes bright UV sources in 291 fields that UVIT detected during its first 2yr of pointed observation, encompassing an area of 58deg^2^. We used the CCDLAB pipeline to reduce the Level 1 data, SExtractor for source detection, and four photometric procedures to determine the magnitudes of the detected sources.
We provided the 3{sigma} and 5{sigma} detection limits for all the filters of UVIT. We describe the details of observation, source extraction methods, and photometry procedures applied to prepare the catalog. In the final UVIT DR1 catalog, we have point sources, extended sources, clumps from nearby galaxies, globular clusters, open clusters, planetary nebulae, and gaseous nebulae.

There are 239520 unique sources in the combined UVIT DR1, of which 70488 sources have FUV magnitudes, and 211410 have NUV magnitudes. We crossmatched and compared noncrowded sources of UVIT with the Galaxy Evolution Explorer and Gaia source catalogs. We provide a clean catalog of the unique sources in various UVIT filters that will help further the multiwavelength scientific analysis of the objects.
