iFIT: 1D surface photometry code

Abstract: iFIT determines the Sérsic law model for galaxies with imperfect Sérsic law profiles by searching for the best match between the observationally determined and theoretically expected radial variation of the mean surface brightness and light growth curve. The technique ensures quick convergence to a unique solution for both perfect and imperfect Sérsic profiles, even shallow and resolution-degraded SBPs. iFIT allows for correction of PSF convolution effects, offering the user the option of choosing between a Moffat, Gaussian, or user-supplied PSF, and is an efficient tool for the non-supervised structural characterization of large galaxy samples, such as those expected to become available with Euclid and LSST.
