  PypeIt is a Python package for semi-automated reduction of astronomical,
spectroscopic data. Its algorithms build on decades-long development of
previous data reduction pipelines by the developers (Bernstein, Burles, &
Prochaska, 2015; Bochanski et al., 2009). The reduction procedure -- including
a complete list of the input parameters and available functionality -- is
provided as online documentation hosted by Read the Docs, which is regularly
updated. (https://pypeit.readthedocs.io/en/latest/). Release v1.0.3 serves the
following spectrographs: Gemini/GNIRS, Gemini/GMOS, Gemini/FLAMINGOS 2,
Lick/Kast, Magellan/MagE, Magellan/Fire, MDM/OSMOS, Keck/DEIMOS (600ZD, 830G,
1200G), Keck/LRIS, Keck/MOSFIRE (J and Y gratings tested), Keck/NIRES,
Keck/NIRSPEC (low-dispersion), LBT/Luci-I, Luci-II, LBT/MODS (beta), NOT/ALFOSC
(grism4), VLT/X-Shooter (VIS, NIR), VLT/FORS2 (300I, 300V), WHT/ISIS.
