Molecfit: A general tool for telluric absorption correction

Context. The interaction of the light from astronomical objects with the constituents of the Earth’s atmosphere leads to the formation of telluric absorption lines in ground-based collected spectra. Correcting for these lines, mostly affecting the red and infrared region of the spectrum, usually relies on observations of specific stars obtained close in time and airmass to the science targets, therefore using precious observing time.
