1.2 mm continuum emission (white contours) superimposed on the 12.5 μm map from (Greenhill et al. 2004, shown in colors). The two runaway stars (BN and I) plus the quasi-static object n are indicated by five-pointed stars (yellow or red) while the 10 sources studied in Paper I are identified and denoted by crosses (white or red; see Paper I for more details). The presumed position of the origin of the explosion is denoted by a multi-pointed red and blue star.
