Best-fit parameters describing the Galactic disc.
| Parameter | Model 1 | Model 2 |
|---|---|---|
| (unit) | ||
| Rd (kpc) | 3.13±0.25 | 4.24±0.32 |
| hɀ,⊙ (kpc) | 0.46±0.03 | 0.18±0.01 |
| log10 Rfl [kpc] | 2.14±0.20 | 0.36±0.04 |
| Rd2 (kpc) | – | 2.66±0.11 |
| hɀ2,⊙ (kpc) | – | 0.48±0.11 |
| fd1 | – | 0.34±0.02 |
Notes. Best-fit values for the parameters fitted to observational data. Model 1 only fits for a single exponential disc that is also flared. Model 2 fits for two exponential disc components, with only one allowed to be flared. The units of the parameters are listed in parenthesis, except for log10 Rfl [kpc] which is dimensionless.
