The observer-frame (z = 1.49) broadband light curves at 5000–7000 Å of SN Refsdal and those of low-redshift SN 1987A–like SNe with a similar shape stretched in time by a factor of 2.49. All light curves are well fit by a piecewise polynomial function. In the fits shown above, the photospheric phase light curve is modeled using a third-order polynomial and the nebular-phase light curve with a second-order polynomial. The uppermost points and best-fitting model are of SN Refsdal’s F125W and F160W combined light curves constructed by shifting and rescaling the measured photometry of its five appearances according to the best-fitting time delays and magnifications relative to that of S1. The F125W and F160W bandpasses correspond approximately to rest-frame V and R bandpasses at z = 1.49, and we plot in respective panels above the measured V and R for the low-redshift examples of SN 1987A–like SNe. For visual clarity we rescale and then subtract constant flux values from the light curves of the nearby SNe.
