Effects of different angular resolutions on the sizes and masses of bound sources in the simulated star-forming regions HD (top), MHD (middle row), and HD^h (bottom). We show the source size function (left), the source mass function (middle), and the cumulative mass function (right), obtained for the y projection of the respective column density maps. The other projections on the x and z directions are displayed in Figs. A.7 and A.8. The fits of the cumulative SMFs were done only for extractions with more than 40 bound sources. We fitted the cumulative SMFs in the mass range corresponding to 5–50% of the source samples; it corresponds to, from top to bottom: 40–128, 39–125, 5–19 M_⊙ for the blue curves, 94–304, 76–329, 11–49 M_⊙ for the red curves, 28–120 M_⊙ for the grey curve, and 87–537 M_⊙ for the purple curve.
