Simulated m_F814W vs. (m_F606W – m_F160W)-0.55(m_F606W – m_F814W) (panel a) and m_F814W vs. C_{F606W,F814W,F322W2} (panel b) pseudo-CMDs. The adopted fractions of 1P, 2P, and mixed binaries provide the best fit with the observations. The selected binaries, which are located within the yellow shaded area of the panel a diagram, are marked with aqua triangles and the remaining binaries with black symbols. For clarity, the number of plotted simulated binaries is three times larger than the number of observed binaries. The lines plotted in panels a and b reproduce the fiducial lines that we defined in Fig. 3. Panels c and d compare the δ_{CF606W,F814W,F322W2} cumulative and the kernel density distributions, respectively, for the observed binaries (magenta lines) and the best-fit simulations (aqua lines). For completeness, we show the distributions of 1P binaries (solid grey lines), 2P binaries (solid black lines), and mixed binaries (dashed grey lines).
