Left: Three-color figure of the Orion region. Blue corresponds to Hα emission \cite{Finkbeiner2003-jq}, yellow is extinction \cite{planck2011-7.0}, and purple is 26Al emission \cite{Diehl1995-jj}. Skeletons of the major molecular clouds in the region \cite{Zucker2021-or} are shown with green, blue, and purple dots corresponding to Orion A, Orion B, and Orion \(\lambda\), respectively. The OBP-B1 stars are shown as white dots. The blue star corresponds to the flux center of Barnard’s Loop \cite{Reynolds1979-zy}, and the orange star indicates the center of expansion of OBP-B1 \cite{Swiggum2021-fe}. Finally, the yellow ring indicates the rough boundary of the dust ring OE-Ring that is likely embedded in Orion-Eridanus.  Right: Two-color combinations of the three main observables. Top right: Hα and extinction; Middle right: right displays Hα & 26Al; Lower right: 26Al and extinction.
