From left to right, first panel: Edge-on stellar density map of particles in the hot disk of Model 2 at t = 0. The density contours trace the whole density distribution of the hot disk in the central regions, the colored map corresponds to the bulge-like part of this distribution (see text for details). Second panel: Edge-on stellar density map at the final time of the simulation of hot-disk particles initially inside the bulge-like region. Third panel: Relative contribution of hot-disk particles initially inside the bulge-like region to the final B/P bulge, as defined by hot-disk particles only. Fourth panel: Relative contribution of hot-disk particles initially inside the bulge-like region to the final B/P bulge as defined by all disk particles, i.e., cold and intermediate disks also included.
