Probability distribution and extinction vs. redshift. The top panel shows the probability distribution for the GRB afterglow, the host galaxy, and a combination of both that favors the high‐redshift scenario. In the bottom panel, the extinction distribution shows a lower ﹩A_{V}﹩ for the high redshift, in the range of what has been observed for LPBs.
