Effects of different angular resolutions on the sizes and masses of the 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 z projection of the respective surface density maps. The other projections on the x and y directions are displayed in Figs. 7 and A.7.
