Time evolution of far-field neutrino rms energies ﹩\sqrt{\langle {{\epsilon }_{{\nu }_{l}}}^{2}\rangle }﹩ (left panel) and luminosities ﹩{L}_{{\nu }_{l}}^{\mathrm{fluid}}﹩ (right panel) measured by an observer comoving with the fluid at 500 km of a collapsing 15 M _⊙ star. The solid lines and dashed lines represent the results obtained by Weakhub (Con) (Weakhub with a conventional set of interactions) and NuLib, respectively. The results obtained using Weakhub (Con) agree well with those using NuLib, with discrepancies of less than ∼10% in rms energies and luminosities for all neutrino species.
