Caption: Figure 6.

Contour map of 26Al emission in the Orion region; see Diehl (2002) for further discussion of 26Al in Orion. The strongest enhancement of 26Al is found in very close proximity to the expansion center of OBP-B1. Molecular cloud spines are shown in green, cyan, and magenta for Orion A, B, and λ, respectively. The orange star denotes the expansion center of OBP-B1. Our model for the extent of OBP-B1 is shown in purple; see Figure 1 for overlays of Hα and dust extinction on top of the 26Al emission.
