Ratios of different physical properties obtained from fitting the simulated LSST data alone and from the UV-FIR SED (e.g., SFR_ratio = SFR_LSST/SFR_{UV − FIR}) as a function of redshift for the ELAIS N1 and COSMOS fields. The properties obtained from the UV-FIR SED fitting are considered as the true values. From the upper left panel we show clockwise the SFR, M_star, L_dust, and M_star comparisons. The dashed lines represent polynomial fits performed on the samples. The points are the median values in each redshift bin, with the median absolute deviation as errors. A ratio equal to zero corresponds to a perfect agreement between the estimates obtained based on the LSST-like sample and the real values. The distributions calculated for ELAIS N1 and COSMOS are comparable within the errors.
