Notes. Table lists results from both the analysis that used all available afterglow SED data, and from the analysis where data covering the Lyman-forest were excluded (i.e. no UV data at wavelengths λ < 121.5 nm). The best-fit Fitzpatrick & Massa (1990, FM90) parameterisations to the SMC, LMC and Milky Way models from Clayton et al. (2003) are shown in italic as a comparison to the best-fit FM90 fits to our data.
