Mass function of the disk-less and disk-bearing candidate members of Dolidze 25 (the latter considered only if inside the ACIS field). The vertical red lines mark the median mass value. The dashed black line is obtained from a linear fit in the log–log space on the mass distribution between 0.8 and 2 M_⊙ (values marked with dotted green lines). The red line shows the normalized Salpeter–Kroupa IMF with α = 2.35 (Kroupa & Weidner 2003).
