The fractional flux distributions of LFBOTs (blue; median and 68% interval) compared to those of SNe II (purple dashed line), Ibc (orange dotted line), SLSNe-I (pink), and LGRBs (yellow). Similar to SLSNe, a large fraction of LFBOTs occur in the faintest region of their host galaxy or outside their host galaxy’s light, and they clearly trend toward lower fractional fluxes than LGRBs and the CCSNe populations.
