| 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. |
