Mock analysis for the L_{AGN, 0.2 − 2.3 keV} (top panel), L_{XRB, 0.2 − 2.3 keV} (middle panel), and fAGN_{0.2 − 2.3 keV} (bottom panel). The Pearson product-moment correlation coefficient is given as an ‘r’ value. The black solid line corresponds to the 1:1 relation, while the red dashed line is the regression line with the equation given in the legend. The magenta star represents the superposition of 44 sources. The red stars are the sources having f_0.25 μm > 0.1 from the initial run described in Sect. 3.
