PypeIt

PypeIt is an open-source Python package for the semi-automated reduction of astronomical slit-based spectroscopy. It turns raw 2D frames into calibrated, sky-subtracted, fully reduced 1D spectra with rigorous error propagation, and supports a broad and growing set of spectrographs (Keck, VLT, Gemini, Magellan, and more).
