Comparison between the masses estimated by the new method, allowing excess emission (allowed masses; Sect. 5.6.1) and the masses inferred from the K_S vs. (H − K_s) CMD (M_CMD) assuming no excess emission. The vertical gray bands represent the range of allowed masses for each source, and the inverted triangles highlight the mass in this interval that corresponds to the least amount of excess emission. The horizontal error bar reflects the uncertainty in mass from photometric errors, except for the points inside the area delimited by the dashed lines, which corresponds to the range of masses in which the models are degenerate: in this area, the horizontal error bars encompass the minimum and maximum possible values from the models. The dashed red line is the identity line.
