Abstract: UVIT onboard AstroSat has extensively observed various UV-bright objects/regions in Far-ultraviolet (FUV) and Near-ultraviolet (NUV) wavebands. A total of 1564 observations are publicly available in ISSDC archive. The analysis of the observed data would unveil a wealth of information on multiple astrophysical objects, such as the Globular cluster (GCs), nearby galaxies, planetary nebulae, etc. We provide the first comprehensive catalog for the fields observed in the first two years from the launch of the UVIT, covering an area of ~58 square degrees. We estimate the background and variation of detection limits of a field with exposure time. Apart from source detection, we model the point spread function (PSF), provide the fluxes and magnitudes of the sources measured using various methods. We then crossmatch our catalogs with various other UV and optical catalogs and provided flags for special fields such as open clusters, globular clusters, nearby galaxy, etc., which would help for any further investigations.
