Version: 1.3.0

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. The reduction procedure - including a complete list of the input parameters and available functionality - is provided by this online documentation.

PypeIt is a set of commands designed to perform the reduction without any additional coding.

This release of PypeIt is designed to be used by both advanced spectroscopists with prior data reduction expertise and astronomers with no prior experience of data reduction. It is highly configurable and designed to be applied to any standard slit-imaging spectrograph, and can accommodate long-slit, multi-slit, as well as cross-dispersed echelle spectra.

What this version provides

What this version is missing (i.e. what we are working on)

  • Full 2D coadd support

  • Additional QA outputs

  • A dashboard to monitor/control PypeIt

  • Keck/HIRES, Keck/ESI support

Users

If you are mainly here to use PypeIt to reduce your observational data then this section is for you. Ideally, you will need to go not much further than the few links in this section take you.

If you have problems, we have a very active “PypeIt Users” Slack workspace. We periodically update the invitation here. If you find a bug or have a feature request, please submit an issue.
