Left panel: absolute bolometric light curve for our 250 M_⊙ PISN model (blue solid curve) and quasi-bolometric and bolometric light curves of superluminous type Ic SN 2010gx (red circles, Inserra et al. 2013), PS1-10awh and PS1-10ky (brown and black triangles, Chomiuk et al. 2011), PS1-10bzj (magenta squares, Lunnan et al. 2013), and SN 2007bi (yellow diamonds, Young et al. 2010). Right panel: absolute R-band (thin green line) and bolometric (thick blue line) light curve for our 250 M_⊙ PISN model, and R-band data for SLSN 2007bi (cyan circles) and PTF-10nmn (red circles) (Gal-Yam 2012b).
