SF efficiency of the molecular gas as a function of the velocity dispersion of the gas (σ) at 90 pc scales. Left and middle panels: cut on the Σ_H2 and Σ_SFR axis for each galaxy, respectively. Colours are as in previous figures. The red and brown points and error bars indicate the mean and mean absolute deviation for the regions in high- and low-N regimes, respectively. Right panel: similar to the left and middle panels, but for non-dual galaxies. The central regions (r < 0.50 kpc) are represented in green and the more external regions in grey. The black and blue points and error bars correspond to the mean and mean absolute deviation values of the central and external regions, respectively. The orange and magenta points and error bars are the mean and mean absolute deviation for all the regions in each panel. The inverted triangles indicate upper limits.
