Mass distribution obtained from parallaxes and SED fits for the sdBs, sdOs, and He-sdOs in our sample. The dashed lines show the normalized histograms for each spectral group and the solid curves are the associated kernel density function. The stars with a composite SED were excluded. In the legend, we indicated the number of stars in parenthesis as well as the average (M̄) and median (M̃) mass for each spectral type. The error bars on top are indicative of the mass uncertainty for each spectral type (see M_err in Table 2).
