Number of galaxies as a function of the number of clumps detected within the selected isophote. We note that we include in this plot single clump galaxies which correspond to galaxies with no substructure or a single central clump. We plot this quantity for two redshift intervals each with its respective value of k_p = 1.5 for 2 < z < 4.5 in gold (left panel) and k_p = 5 for 4.5 < z < 6.0 in purple (right panel). On each panel we show the number of clumps for the VUDS targets.
