Density histograms of AV (left), ﹩{R}_{\widetilde{VI}}﹩ (middle), and α (right) within the overlap of VV 191b with the restrictions as mentioned in Figure 7. The best log-normal fits of AV and ﹩{R}_{\widetilde{VI}}﹩ and a Gaussian fit of α are overlaid in black. The distributions of the dust parameters with an even stricter threshold, AV > 0.25 and S/NF090W ≥ 3, are shown in orange, with their best-fit probability density function (pdf) fits overlaid in gray. The mean and the standard error of the distributions (not the fits) of ﹩{R}_{\widetilde{VI}}﹩ and α are given in Table 2.
