Surface of section in the 2D simulations. The two panels from left to right show the surface of section of E = −1, −0.4, slice, respectively, in the ax-2D-random simulations. The stellar mass of particles with energy less than each E in the axisymmetric galaxy is, respectively, 10% and 45% of the total stellar mass. The dots are colored by ﹩{fz}/{fx}﹩, in which 1:1 loops are denoted by red dots, 4:3 pretzels by cyan dots, 3:2 fishes by magenta dots, 2:1 bananas by green dots, chaos by gray dots, and other resonances by black dots. The 1:1 loop is always dominant. Chaotic orbits always occupy the lower angular momentum part of the figure, as they interact with the SMBH.
