Column density maps of all the selected outputs described in Table 1. Each block corresponds to a given simulation (the identifier is indicated in the lower left corner of the block). Each block displays column density maps integrated along the x, y, and z axes (from top to bottom: y-z, x-z, and x-y maps, respectively), and for a snapshot at m_sink = 0.1, 0.2, and 0.3 M_⊙ (from left to right). The projection and evolutionary step are shown at the top of each individual plot. Higher resolution figures for individual simulations are available online.
