Panel a: reproduction of the m_F814W vs. (m_F336W – m_F814W)-0.40 (m_F606W – m_F814W) pseudo-CMD of stars in the central field plotted in Fig. 5. Panel b: m_F814W vs. C_{F336W,F435W,F814W} pseudo-CMDs. Panel c: Verticalized m_F814W vs. δ_{CF336W,F435W,F814W} diagram for the MS-MS binaries. The binaries in panel a are represented with magenta triangles in panels a, b, and c. The red and blue lines superimposed in panel b are the fiducials of 1P and 2P_δ stars, respectively, while the corresponding fiducial lines of equal-luminosity binaries are represented with dotted lines in panels b and c. Panels d and e: Cumulative and kernel-density δ_{CF33eW,F435W,F814W} distributions, respectively, for the observed binaries (solid magenta lines), for the simulated binaries that provide the best match with the observations (solid aqua lines), 1P binaries (solid grey lines), mixed binaries (dashed grey lines), and 2P binaries (solid black lines).
