Reliability of the SFR estimations using the X-CIGALE mock catalogues for sources with and without FIR bands. Top panel: Comparison of SFR measurements with and without FIR photometry, for the high-z sources that have FIR coverage and satisfy our quality selection criteria (Sect. 3.2). The dashed lines lines present the 1:1 relation. The parameter calculations are in good agreement based on the Pearson correlation factor, ρ given in the plot. Middle panel: Estimated SFR based on the mock catalogues compared to the true values provided by the best-fit model for the three fields used in our analysis. The filled (open) symbols represent the X-CIGALE runs with (without) FIR data. The dashed line represent the 1-to-1 relation to assist the plot interpretation, while in each plot we give the linear Pearson correlation coefficient (ρ) of the combined sample. Bottom panel: Corresponding distributions of the difference between estimated and true values. We provide also the mean and standard deviation for each case.
