easyspec streamlines long-slit spectroscopy. The code reduces raw long-slit spectroscopic data, and extracts and calibrates spectra in wavelegnth and flux. It can fit a model to each line of the spectrum with a MCMC approach and recover physical quantities such as redshift, dispersion velocity, FWHM, and line flux. easyspec can also be used to fit two Gaussian components, explore the MCMC posterior distributions, and stack several spectra of the same target collected with different instruments.
