Left: distribution of the selected MUSIC clusters in the mass-redshift plane. The mass and redshift bins considered are identical to those of NIKA2 SZ large program. The redshifts in each bins are generated randomly using a uniform distribution within their respective boundaries for display reasons. Morphologically relaxed and disturbed clusters are indicated by blue dots and red triangles, respectively. Right: distributions of the morphological indicators computed for the selected MUSIC clusters for the relaxed (blue) and disturbed (red) subsamples. The vertical dash-dotted lines enclose the population of clusters with a hybrid dynamical state (see Sect. 4.1).
