Gofio

Abstract

GOFIO is a DRS written for the GIANO-B infrared spectra. It is installed at the Telescopio Nazionale Galileo (TNG) and it is part of the online reduction pipeline running at the telescope, but it can work also as a standalone offline DRS without a graphical interface, which allows to reduce the ramp-processed raw files available in the TNG archive. GOFIO processes all the calibration and scientific images, observed both in the nodding and stare mode. The reduction process includes bad pixel and cosmic removal, flat-field and blaze correction, optimal extraction, wavelength calibration with U-Ne lamps, nodding or stare group processing. A logfile of the whole reduction process is created and stored in the reduction directory. In the offline mode, the reduction process can be completely customized, but it is suggested to use only the command line options, unless having a great familiarity with the instrument and its settings.
