Comparison of the H07 template and the best fitting models when including only certain bands. Points included in the χ² analysis are shown as solid circles. Unfilled circles show the remainder of the light curve for reference. In each case, the template is first detected one day after explosion and extends to approximately three weeks later. Panel a: best matching model parameters are given when fitting only the B-band light curve of the H07 template. Panel b: fitting only the R-band, we find the best model has changed. Panel c: best matching model when including both the B- and R-bands. Panels d and e: ⁵⁶Ni distributions for the best fitting models in mass- and velocity-space, assuming the noted filters are observed.
