Spectra of neutrino opacities defined in Equation (71) as a function of neutrino energy ε of the weak interactions included in Weakhub at thermodynamic point (I) in Table 3, which corresponds to the central region of s15s7b2 in Woosley & Weaver (1995). Note that the absorption opacities are computed using the full kinematics approach and all available corrections, and the scattering opacities incorporate all of the corrections as mentioned. Absorption processes, elastic scattering, inelastic scattering, and pair processes are represented by red, green, orange, and blue, respectively. We rescale opacities by multiplying 10⁸ for ν e ⁺ inelastic scattering, 10¹⁰ for e ⁻ e ⁺ annihilation, 10¹⁵ for N–N bremsstrahlung, 10⁷ for the plasma process, and 10⁶ for the nuclear de-excitation process, respectively.
