Peak absolute magnitudes plotted as a function of wavelength, where the effective wavelengths of the CSP-I passbands are indicated with vertical lines. At optical wavelengths, SE SNe generally show higher values in the blue passbands compared to the red passbands. Among the NIR passbands, SE SNe exhibit similar peak absolute magnitudes and the values at NIR wavelengths are lower than those in the optical. SNe IIb, Ib, Ic, and Ic-BL are represented in green, blue, red, and magenta, respectively.
