I-band light curve of OGLE-2014-SN-131 alongside Type Ic SN 2011bm (Valenti et al. 2012), compared to template Type Ibn and Type Ibc light curves (Taddia et al. 2015), as well as to the SN Ibc template scaled to the SLSN sample (Nicholl et al. 2015). As examples, the phenomenological fits from Bazin et al. (2011) used in the broadness comparison for the two SNe have been over-plotted as dashed lines. The broadness parameter plotted in Fig. 7 is also indicated with a solid line for both SNe. Both OGLE-2014-SN-131 and SN 2011bm have broader light curves compared to their respective classes.
