Summary of the parameters used in the Toomre length estimation and the resulting estimates for the sample galaxies.

Galaxy Σg (Mpc−2) v (km s−1) r (kpc) lT (pc)
NGC 1566 2.7 160 8.3 617
NGC 5194 24.0 220 5.5 1274
NGC 5457 1.7 180 8.5 322
NGC 7793 2.6 125 2.7 105

Notes. Molecular hydrogen density (Σg) and flat rotation velocity (v) adopted directly from M21, median galactocentric radius of SFCs (r) and the estimated values of the Toomre length (lT) of the sample galaxies.
