Comparison of the SFR and M_* measurements (left and right panel, respectively) for the estimated and true values from the mock analysis. Blue triangles show the results for type 1 X-ray AGN and red circles correspond to type 2 X-ray AGN. Sources are classified based on optical spectra. The black solid line shows the 1:1 relation. Restricting the measurements to those sources with statistical significance, §/N > 2 (open circles), effectively reduces the scatter of the calculations.
