Spire 250 μm map of the region towards NGC 3077 overlaid with contours from observations of the CO (1 → 0) line obtained with the IRAM 30 m telescope (Heithausen 2002; Walter & Heithausen 1999; Heithausen & Walter 2000). Observed CO positions are marked by Xs. Contours are from 0.1 K km s-1 every 0.1 K km s-1. Solid contours show emisson from the tidal arm cloud associated with NGC 3077 (Walter & Heithausen 1999; Heithausen & Walter 2000), whereas dashed contours show emission from the Galactic small area molecular structure SAMS1 (Heithausen 2002). There is further CO emission towards the position , which is marked by the black triangle.
