Caption: Figure 5.

Molecular surface density (open blue circles) and Toomre Q-parameter (filled red squares, Q Toomre = (κσ 0/π GΣ mol gas)) in a 0 farcs75 software slit along the major axis of the galaxy. Here κ is the epicyclic frequency, κ 2 = R × d(( v/ R) 2)/ dR + 4 × ( v/ R), v is the rotation velocity at radius R, σ 0 is the average local velocity dispersion (after removal of rotation and correction for instrumental resolution) and Σ mol gas is the molecular gas surface density.
