PyLongslit: a simple manual Python pipeline for processing of astronomical long-slit spectra recorded with CCD detectors
Kostas Valeckas, Johan Peter Uldall Fynbo, Jens-Kristian Krogager +1
We present a new Python pipeline for processing data from astronomical long-slit spectroscopy observations recorded with CCD detectors. The pipeline is designed to aim for simplici…
