Impact of the photometric redshift prior in the estimated parameters. We present the estimated probabilities of Q_SF (upper panel), α_SF (central panel), and β (lower panel). The coloured histograms are the individual results obtained with BPZ2 prior (blue), constant prior (green), and cosmic volume prior (orange). The combined final probability is the black histogram, with the best Gaussian fit to the distribution in solid red. The parameters of this Gaussian fit are labelled in the panels.
