Upper panels: histogram of the difference between the estimated values of M_star and SFR and the exact values from the mock catalogue. Black line: whole dataset, blue line: without IB data, green filled histogram: without NIR data, red filled histogram: without IR data, Lower panel: SSFR estimated with SED fitting are compared to the true values of the SSFR. Black point: whole dataset, green dots: without NIR data, red dots: without IR data. Results without IB are not shown since they are indistinguishable from those without IR data.
