Same as Fig. 3, but for the median evolution of the ex situ stellar mass. Top: ex situ mass normalized by the final ex situ mass (solid) or final (ex situ + in situ) stellar mass (i.e., ex situ stellar mass fraction, dashed). All masses are measured over the entire subhalo. Center and bottom: ex-situ stellar mass from major mergers (stellar mass ratio > 1/4, solid lines), intermediate mergers (stellar mass ratio between 1/4 and 1/10, dashed lines), and minor mergers (stellar mass ratio below 1/10, dotted lines).
