Same as the second row of Fig. 1 but for all isolated giant GalMer galaxies. Contour levels are the same for all plots and the time is t = 1 Gyr. The locations of the bar’s corotation and OLR are indicated by the dotted and solid lines, respectively. The rightmost panel shows the only disk lacking a central bar. In this case, resonance overlap from strong multiple spirals gives rise to a smooth ΔL distribution.
