Abstract:
The 4-m International Liquid Mirror Telescope (ILMT) located at the ARIES Observatory (Devasthal, India) has been designed to scan at a latitude of +29◦ 22’ 26” a band of sky having a width of about half
a degree in the Time Delayed Integration (TDI) mode. Therefore, a special data-reduction and analysis pipeline
to process online the large amount of optical data being produced has been dedicated to it. This requirement
has led to the development of the 4-m ILMT data reduction pipeline, a new software package built with Python
in order to simplify a large number of tasks aimed at the reduction of the acquired TDI images. This software
provides astronomers with specially designed data reduction functions, astrometry and photometry calibration
tools. In this paper we discuss the various reduction and calibration steps followed to reduce TDI images obtained in May 2015 with the Devasthal 1.3m telescope. We report here the detection and characterization of
nine space debris present in the TDI frames.
