Correlation matrix between observed and physical parameters of SNe II. For each pair, the Pearson correlation coefficient is given and is colour-coded. The observed parameters shown are: pd, optd, Cd, s₁, s₂, s₃, M_bol, end, M_bol, tail, (g − r)₁₅, (g − r)₇₀, velocities of H_α, H_β, and Fe IIλ5169, pEW(H_α) of absorption component, pEW(H_α) of emission component, pEW(H_β), pEW(Fe IIλ4924), pEW(Fe IIλ5018), pEW(Fe IIλ5169), and a/e.
