Parameters of the best model for each band and each seed (represented by colors as given in legend) for the initial band-by-band fit (colored circles) and final band-by-band fit (colored crosses) as determined by the maximum likelihood. The seed used as the starting position for the final fit in each band is given a black border. Overplotted as lines are the best and median fit for the polychromatic model. The shaded region is the 1σ errors on the median fit parameters.
