|||
| warp | γ warp+ | pc kpc-1 | 0.09 |
| γ warp− | pc kpc-1 | 0.09 | |
| R warp | pc | 8400 | |
| θ warp | rad | 0.0 | |
| flare | γ flare | kpc-1 | 0.05 |
| R flare | pc | 8400 | |
| scale length | kp1 | pc | 5000 |
| kp2...7 | pc | 2170 | |
| χ2 | – | – | 33.32 |
Notes. γwarp+ and γwarp− refer to the warp slope at second and third quadrants, respectively. For scale length, kp1 refers to stars with age class AC = 1, and kp2...7 to older ages, e.g., a unique value for the scale length of stars with AC ≥ 2.
