PyLongslit processes astronomical long-slit spectral data recorded with CCD detectors. The software performs standard calibration steps on raw two-dimensional long-slit FITS frames, producing wavelength-calibrated 2D spectra and one-dimensional spectra for point-like sources. It supports extraction of flux-calibrated 1D spectra after detector calibrations such as bias subtraction, flat-fielding, and wavelength mapping, and includes quality-assessment plots to assist users in evaluating intermediate and final products. Designed to be instrument independent, PyLongslit works with generic long-slit spectrograph data meeting basic format and calibration frame requirements.

FRB performs calculations, estimations, analysis, and Bayesian inferences for Fast Radio Bursts, including dispersion measure and emission measure calculations, derived properties and spectrums, and Galactic RM.
