Table 2.
Maximum azimuthal residual variations Δmax [X/H] for oxygen, europium, iron, and barium predicted by models B1 and B2 at the respective co-rotations of the outermost spiral chunk (characterised by angular velocity Ωs, 3 and the co-rotation radius R3, cor.).
| Models | Ωs, 3 | R3, cor. | Δmax [O/H]3, cor. | Δmax [Eu/H]3, cor. | Δmax [Fe/H]3, cor. | Δmax [Ba/H]3, cor. |
|---|---|---|---|---|---|---|
