Σ_H2 contours in M_⊙ pc^-2 derived from ¹²CO(1−0), ¹²CO(2−1), and ¹²CO(3−2) overlaid on Σ_SFR images in M_⊙ yr^-1 kpc^-2 at the intrinsic spatial resolution of the ¹²CO data and with pixel sizes equal to the ¹²CO resolution. The beams are plotted (in yellow) in the lower left corners of maps and their values are listed in Table 2. (Δα, Δδ)-offsets are with respect to the dynamical center of each galaxy. Σ_H2 contours are drawn starting from noise levels >3σ with contour spacings that are whole multiples of >3σ.
