Upper left panel: distributions of Type II breaks associated with different structure components of the galaxies, as a function of stellar mass. Upper right panel: distribution among Hubble types. The Type II breaks connected to spirals in the upper panels includes both the breaks seen at the spiral outer edges (S) and the breaks seen near prominent star formation regions inside the spirals (BS). Lower panels: sizes of the structures (Laurikainen et al. 2011; Comerón et al. 2014; Herrera-Endoqui et al. 2015) are correlated with the : in the left panel for rings and lenses, and in the right panel for spiral structures. The dashed line indicates where feature radius equals , and the solid line indicates where equals 0.5 × feature radius. The letter in parenthesis is the same as the Type II break association given in Table 3, and the number given in parenthesis indicates the number of breaks included in each group.
