Comparison of the radial profiles of several quantities against the isotropic radial coordinate r at the moment of core bounce of a collapsing 20 M _⊙ star, with three sets of interactions in Weakhub. The dashed–dotted lines, dashed lines, and solid lines correspond to the results with interactions of conventional set (Con), advanced set (I) (Adv.I), and advanced set (II) (Adv.II), respectively. The profiles include rest mass density ρ, matter temperature T, electron fraction Y _e , and neutrino rms energy observed in the fluid comoving frame ﹩\sqrt{\langle {\epsilon }_{{\nu }_{l}}^{2}\rangle }﹩. All results quantitatively agree well with discrepancies of less than 5%, except for the approximately 28% and 40% higher values of ﹩\sqrt{\langle {\epsilon }_{{\bar{\nu }}_{e}}^{2}\rangle }﹩ and ﹩\sqrt{\langle {\epsilon }_{{\nu }_{x}}^{2}\rangle }﹩, respectively, outside the shocked region for the case of Adv.II.
