i-band light curve of SN 2019oyw presented along with three other well-studied GRB-SN events: SN 1998bw, SN 2006aj, and SN 2010bh. Light curves for the given SNe have been de-reddened (Galactic + Host absorption) and also magnitude values and phase have been shifted to the rest-frame. The constrained value of the peak brightness of SN 2019oyw is close to that estimated in the case of SN 1998bw. SN 2019oyw exhibits a post-peak decay rate close to that expected for the radioactive decay of 56Ni–> 56Co (black dotted line). The shaded region marks the 1σ contour for the corresponding best-fit light curve.
