Main simulation parameters for the galactic simulation.
| Parameter | Value |
|---|---|
| Simulation time/age | 12 Gyr |
| Step size | 10 Myr |
| Galactic disc ring number | 100 |
| Galactic disc ringwidth | 0.2 kpc |
| Total mass at start (M0) | 108 M⊙ |
| Final scalelength (Rf) | 4 kpc |
| Early infall mass (M1) | 40 × 109 M⊙ |
| Early infall timescale (b1) | 1 Gyr |
| Long infall mass (M2) | 100 × 109 M⊙ |
| Long infall timescale (b2) | 9 Gyr |
Notes. The definition for the infall is the same as in Eq. (2) of Schönrich & Binney (2009).
