AV, ﹩{R}_{\widetilde{VI}}﹩, and α distributions (filled histograms) from regions A, B, and C (regions shown in Figure 8) of VV 191b. Region A most resembles a typical spiral arm, Region B is similar to a tendril branch of a spiral arm, and Region C is the edge of the galaxy disk. The best-fit model of the pdf of the distributions of the entire overlap of VV 191b (see Figure 6) is overlaid in black, scaled to roughly match the histogram peaks of the three regions.
