Introducing GOFIO: a DRS for the GIANO-B near-infrared spectrograph

The NIR echelle spectrograph GIANO-B at the Telescopio Nazionale Galileo is equipped with a fully automated online DRS: part of this pipeline is the GOFIO reduction software, that processes all the observed data, from the calibrations to the noddingor stareimages. GOFIO reduction process includes bad pixel and cosmic removal, flat-field and blaze correction, optimal extraction, wavelength calibration, noddingor staregroup processing. An offline version of GOFIO will allow the users to adapt the reduction to their needs, and to compute the radial velocityusing telluriclines as a reference system. GIANO-B may be used simultaneously with HARPS-N in the GIARPS observing mode to obtain high-resolution spectra in a wide wavelength range (383-2450 nm) with a single acquisition. In this framework, GOFIO, as part of the online DRS, provides fast and reliable data reductionduring the night, in order to compare the infrared and visible observations on the fly.
