Top: Cumulative offsets normalized to r₅₀ for two samples of long GRB hosts galaxies observed with HST (Lyman et al. 2017; Blanchard et al. 2016). The offset for GRB 171205A is the measured offset, not the deprojected offset used elsewhere in the paper since the comparison samples are mostly irregular galaxies where deprojection is hampered. Bottom: Cumulative distribution of the fraction of brightest pixel at the GRB site in different GRB host galaxies from the same sample as in the plot above. The dashed line indicates the GRB site following the general light distribution. The two lines indicate the light fraction for the site of GRB 171205A in the F300X filter (UV) and F606W filter (∼R-band).
