Maps of SFE (color) superposed on the ¹²CO(J = 1–0) integrated intensity obtained by COMING (white contour) in NGC 3367 (left) and NGC 7479 (right). The contour levels are 3, 6, and 10 K km s⁻¹ for NGC 3367 and 5, 10, 20, 30, and 50 K km s⁻¹ for NGC 7479, respectively. The blue ellipse indicates r/r₂₅ = 0.3. The white circle at the bottom left-hand corner indicates the angular resolution of the maps, 17″. The dashed magenta line in NGC 3367 indicates the position of the bar.
