Selected representative orbits for the 3 d.o.f. Milky Way system given by the potential Eq. (1).

Orbit Initial location (x0,y0,z0), (Vx0,Vy0,Vz0) Dominant behaviour

HF1 High z, far from centre, low velocity (10.0,0.0,10.0) (0.0,50.0,0.0) Chaotic
HF2 High z, far from centre, high velocity (10.0,0.0,10.0) (0.0,200.0,0.0) Mainly regular
HC1 High z, close to centre, low velocity (5.0,0.0,10.0), (0.0,50.0,0.0) Chaotic
HC2 High z, close to centre, high velocity (5.0,0.0,10.0) (0.0,200.0,0.0) Mainly regular

LF1 Low z, far from centre, low velocity (10.0,0.0,0.5) (0.0,50.0,0.0) Chaotic
LF2 Low z, far from centre, high velocity (10.0,0.0,0.5) (0.0,200.0,0.0) Regular
LC1 Low z, close to centre, low velocity (5.0,0.0,0.5) (0.0,50.0,0.0) Highly chaotic
LC2 Low z, close to centre, high velocity (5.0,0.0,0.5) (0.0,200.0,0.0) Regular

Notes. The dominant behaviour label refers to the intensity of the chaos for most halo parameters.
