Parameters of initial condition distributions for the forward orbits integration.

Coordinate Distribution Center Dispersion, width

R uniform 4.0 kpc 1.0 kpc
φ 0–2π with equidistant distribution
z normal 0 kpc 0.05 kpc
vR normal 0 km s-1 10 km s-1
vφ normal vc(R) 6 km s-1
vz normal 0 km s-1 4 km s-1

Notes. We used cylindrical galocentric coordinates – galocentric radius R, azimuth φ, vertical coordinate z and corresponding velocities vR, vφ, vz. The tangential velocity vϕ was calculated as the circular velocity vc(R) in the axisymmetric potential as described in Sect. 2.1 at a given radius and then a random velocity with a dispersion of 6 km s-1 was added.
