MF slope obtained using the fitting approach (Eq. (24), top) and the MLE (bottom) between 0.3 and 0.7 M_⊙ over time for the main model. Both the MFs as seen by an observer who cannot resolve the binaries (dashed) and the actual real MFs (solid) of the resolved SC, T1, and T2 are shown. The coloured areas show the 1σ confidence span. The canonical value of 1.65 is shown as a dotted black line.
