Panel a: spectra of PS16cgx compared to a selection of Type Ic SNe. The comparison events include the GRB associated Type Ic-BL event SN 1998bw (Patat et al. 2001); non-GRB associated Type Ic-BL event SN 2002ap (Modjaz et al. 2014); and normal Type Ic events, SN 2007gr (Hunter et al. 2009), and SN 2004aw (Taubenberger et al. 2006). The strong host galaxy emission lines of PS16cgx are labelled. Panel b: spectra of PS16cgx compared to a selection of Type Ia SNe. The comparison events include SN 2005eq, SN 2005na (Blondin et al. 2012), SN 2006py (Folatelli et al. 2013), and SN 2011fe (Pereira et al. 2013). In both panels the spectra have been corrected for line-of-sight reddening and to the rest-frame wavelength. The wavelengths of the main telluric bands in the spectra of PS16cgx are indicated with a ⊕ symbol. Comparison data were obtained via WISeREP (Yaron & Gal-Yam 2012).
