Distribution of the ALMAGAL clumps hosting at least 10 cores in different bins of the ratio L/M. The colored histograms show the systems were a signature of MS is found, with different colors referring to the different intervals of L/M ratio, i.e., orange L/M ≤ 2 L_⊙/M_⊙, green 2<L/M ≤ 10 L_⊙/M_⊙ and purple L/M>10 L_⊙/M_⊙. The solid black line, which refers to the right y-axis scale, indicate the relative fraction of systems with MS with respect to the observed ones in bins of L/M, while the dot-dashed line shows the average occurrence fraction of MS systems in the three intervals of L/M.
