We developed a pipeline for galaxy profile fitting that uses multiple images at different wavelengths simultaneously, while connecting galaxy properties over wavelength in a smooth and physical way, in order to improve the quality of these fits and extend the galaxy sample available for scientific analysis to fainter magnitudes (and therefore higher redshifts). There are already a few nice papers out there using these data, using more accurate single-sérsic fits and we’re working on the analysis of our Bulge-Disk-decompositions. It turns out, colour information in data is really useful to separate the different galaxy components and derive e.g. more accurate Colour-Magnitude or Magnitude-Size-Relations for the individual galaxy components.
