Average shock radius (left column) and the PNS radius (right column) for simulations based on five progenitors with ZAMS masses of 11, 12, 13, 14, and 15 solar masses. We performed three simulations for each progenitor, using different neutrino transport methods. The dashed red line corresponds to simulations with fully energy-dependent transport, the green lines indicates simulations using the gray scheme of Foucart et al. (2016), and the blue lines show results from simulations using the gray transport proposed in this work. Each row corresponds to a given progenitor; the progenitor model is indicated in the top left corner of each row. The simulations were performed with the SFHo EOS.
