Best-fit parameters and uncertainties for the Brick field data (Fig. 1).
| Brick field | ||
|---|---|---|
| Perpendicular | Bulge | NSD |
| μb (mas yr−1) |  |
 |
| σb (mas yr−1) |  |
1.53 ± 0.12 |
| ampb | 0.45 ± 0.06 | 0.53 ± 0.06 |
| Parallel | Bulge | NSD |
| μl (mas yr−1) |  |

Notes. μ, σ, and amp are the mean velocity, standard deviation, and amplitude of the Gaussians fitted to the distribution. Uncertainties correspond to a 1σ spread of each parameter’s posterior distribution. Perpendicular and parallel indicate the proper motions’ direction in relation to the Galactic plane.
