  We present the AstroSat UV Deep Field South (AUDFs), an imaging survey using
the wide-field Ultraviolet Imaging Telescope on board AstroSat. AUDFs covers
$\sim 236$ arcmin$^{2}$ of the sky area, including the Great Observatories
Origins Deep Survey (GOODS) South field in F154W and N242W filters. The deep
and shallow parts of AUDFs have exposure time $\sim 62000$ and $\sim31000$ sec
respectively, in the F154W filter, while in the N242W filter, they are $\sim
64000$ and $\sim34000$ sec. These observations reached a $3\sigma$ depth of
27.2 and 27.7 AB mag with a $50\%$ completeness limit of 27 and 27.6 AB mag in
the F154W and N242W filters, respectively. With the acquired depth, AUDFs is
the deepest far and near-UV imaging data covering the largest area known to
date at 1.2" - 1.6" spatial resolution. Two primary catalogs were constructed
for the F154W and N242W filters, each containing 13495 and 19374 sources
brighter than the 3$\sigma$ detection limit, respectively. Our galaxy counts
power-law slope $\sim0.43$~dex~mag$^{-1}$ in the N242W filter matches well with
HST/WFC3/UVIS observations.
  A wide range of extra-galactic science can be achieved with this unique data,
such as providing a sample of galaxies emitting ionizing photons in the
redshift range $z \sim 1 - 3$ and beyond; constraining the UV luminosity
function, investigating the extended-UV (XUV) emission around star-forming
galaxies and UV morphologies for $z < 1$. The UV catalog will enhance the
legacy value of the existing optical/IR imaging and spectroscopic observations
from ground and space-based telescopes on the GOODS South field.
