  The International Liquid Mirror Telescope (ILMT) is a 4-meter class survey
telescope that has recently achieved first light and is expected to swing into
full operations by 1st January 2023. It scans the sky in a fixed 22' wide strip
centered at the declination of $+29^o21'41''$ and works in Time Delay
Integration (TDI) mode. We present a full catalog of sources in the ILMT strip
that can serve as astrometric calibrators. The characteristics of the sources
for astrometric calibration are extracted from Gaia EDR3 as it provides a very
precise measurement of astrometric properties such as RA ($\alpha$), Dec
($\delta$), parallax ($\pi$), and proper motions ($\mu_{\alpha^{*}}$ &
$\mu_{\delta}$). We have crossmatched the Gaia EDR3 with SDSS DR17 and
PanSTARRS-1 (PS1) and supplemented the catalog with apparent magnitudes of
these sources in g, r, and i filters. We also present a catalog of
spectroscopically confirmed white dwarfs with SDSS magnitudes that may serve as
photometric calibrators. The catalogs generated are stored in a SQLite database
for query-based access. We also report the offsets in equatorial positions
compared to Gaia for an astrometrically calibrated TDI frame observed with the
ILMT.
