[ascl:2209.011] GaLight: 2D modeling of galaxy images

GaLight (Galaxy shapes of Light) performs two-dimensional model fitting of optical and near-infrared images to characterize the light distribution of galaxies with components including a disk, bulge, bar and quasar. Light is decomposes into PSF and Sersic, and the fitting is based on lenstronomy (ascl:1804.01). GaLight's automated features including searching PSF stars in the FOV, automatically estimating the background noise level, and cutting out the target object galaxies (QSOs) and preparing the materials to model the data. It can also detect objects in the cutout stamp and quickly create Sersic keywords to model them, and model QSOs and galaxies using 2D Sersic profile and scaled point source.
