Reliability of the M_∗ estimations using the X-CIGALE mock catalogues for sources with and without MIR bands. Top panel: Comparison of stellar mass measurements with and without NIR photometry, for the high-z sources that have NIR coverage and satisfy our quality selection criteria (Sect. 3.2). The dashed lines lines present the 1:1 relation. The parameter estimations are in very good agreement considering the Pearson correlation factor, ρ, given in the plots. Middle panel: Estimated stellar mass 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-XIGALE runs with (without) NIR data. Bottom panel: Distributions of the difference between estimated and true values. The mean difference and its dispersion are very similar in the two runs (with and without NIR photometry).
