Radial trends of the expected mass of clumps (left) and the most unstable effective azimuthal wavenumber (right) for the galaxies with Q_3D < 1. The shaded areas show the range of values for 0.5 ≤ f ≤ 1 (see Sect. 4.4 for details). In each panel, we also report the expected clump mass ⟨M_clump⟩ (blue dotted line) with the uncertainty given by 0.5 ≤ f ≤ 1 and the corresponding expected number of clumps N_clump.
