The physical galactocentric offset (left) and host-normalized offset (right) distributions of LFBOTs (blue; median and 68% interval) compared to those of SNe II (purple dashed line), Ibc (orange dotted line), Ibn (green), SLSNe-I (pink), and LGRBs (yellow). LFBOTs have similar physical offset distributions to SNe II, Ibc, and Ibn, and are more offset than SLSNe-I and LGRBs. Additionally, LFBOTs have larger host-normalized offsets than LGRBs, SNe Ibc, and SN Ibn and more similar distributions to SNe II and SLSNe-I.
