Fig. 6.
Maps of the best test-particle simulation, s2c, with Ωp = 20 km s−1 kpc−1 and A2 = 40 km2 s−2: Panel a: relative surface density (normalized to unity in azimuth). Panel b: Vr = −v (i.e., positive for motion toward GC), and Panel c: Vθ. The imposed spiral potential minima are indicated by dashed lines.
