Top: bolometric light curve for models a4pm1 (the dashed line gives the instantaneous magnetar power), m15mlt3 (standard SN II-P), and R190NL (pair-instability SN). Bottom: same as the top, but showing the absolute R-band magnitude. I also add the observations of iPTF14hls corrected for distance and time dilation. The thin blue line in both panels corresponds to model a4pm1 without magnetar power.
