Comparison between accreted stellar mass and all types of fine structures. Upper panel: red line represents evolution of accreted mass. Arrows indicate when mergers occur. Red numbers over bold arrows correspond to intermediate mass and major mergers. Lower panel: evolution of highest value of three projections in each fine structure. Blue dotted line is for tidal tails, green dotted and dashed line is for streams and black dashed line is for shells. Purple dotted and dashed lines in both panels indicate the correlation between main mergers and substructures.
