JUDE: An alternative UVIT pipeline

The Ultraviolet Imaging Telescope (UVIT) was launched as part of the multi-wavelength Indian ASTROSAT mission on 28 September, 2015 into a low Earth orbit. A 6-month performance verification (PV) phase has ended in March 2016, and the instrument is now in the general observing phase. The UVIT operates in three channels, visible (3200 -- 5500~\AA), NUV (1800 -- 3000~\AA) and FUV (1300 -- 1800~\AA), each with a choice of broad-band and narrow-band filters; and has NUV and FUV gratings for low-resolution spectroscopy. We have written a software package to convert the Level~1 data from the UVIT into scientifically useful photon lists and images. The routines are written in the GNU Data Language (GDL) and are compatible with the IDL software package. We use these programs in our own scientific work, and will continue to update the programs as we gain better understanding of the UVIT instrument and its performance. This package is released as an open source software.
