Notes. The bias (expressed as a percentage) is defined as the relative error between the median of the output distribution of the photometry algorithm and the injected input. The 1σ uncertainty (also expressed as a percentage) represents the discrepancy around the most probable value of the output distribution. Those quantities are given in the various cases corresponding to the output flags provided by the algorithm. Statistics of the temperature and spectral index are also given here, to show the impact of the observed error on flux densities.
