Luminosity−decline relationships of relativistic SNe IcBL (GRB-SNe: filled circles; SNe IcBL: filled triangles) in filters (purple), (green), and (red), from [44]. Solid black lines and points correspond to absolute magnitudes calculated for luminosity distances, while coloured points and lines correspond to absolute magnitudes calculated for those events where independent distance measurements have been made to the SN’s host galaxy. The correlation coefficient for each dataset is shown (in black and in their respective colours) as well as the best-fitting luminosity−decline relationship determined using a bootstrap method and the corresponding rms () of the fitted model. It is seen that statistically significant correlations are present for both the GRB-SNe and combined GRB-SN and SN IcBL samples.
