Same field of view as in Figure 1 is shown except that here the ratio of the F502N over F656N images is shown. The solid lines depict radial ionization shadow features that project back toward θ ¹ Ori C and the dotted lines depict significant, nearly linear features that do not project back to θ ¹ Ori C. Almost all of the solid-line features have an identified proplyd, which is the occulting source and in this case the designation of the proplyd is given, adjacent to the proplyd's position. The exception to this rule is the ionization shadow feature lying beyond the HH 202-S shock. The white dashed line shows the boundary where radial shadows begin.
