Spectrographs

Overview

Below we describe all of the spectrographs with existing code infrastructure that enables PypeIt to reduce the data. Most of these spectrographs are “supported,” meaning that the reduction of the relevant data has been well-vetted by PypeIt developers. “Unsupported” spectrographs are in-development; however, the development timescale is undefined.

For instructions on how to add a new spectrograph see: New Spectrograph. Additional details for each spectrograph are provided via the links below.
