Fig. B.2


Examples of photon trajectories. The left panel shows a photon escaping through the random walk from a static medium with (NHI,cl,fc) = (1020 cm-2, 100). In the central panel the photon escapes in an excursion [(NHI,cl,fc) = (1017 cm-2, 100)] after a random walk and in the right panel nearly directly through excursion/single flight due to movement of the clumps [( NHI,cl,fc,σcl) = (1017 cm-2, 100, 100 km s-1)]. In each panel, the escape frequency x is shown along with the total number of scatterings n, and the distance traveled d. In addition, the color coding represents the frequency of the photon (truncated at ± 5). An animated version of this figure is available online.
