Filters applied to the globular clusters and the reference SMC field in this paper used for the 47 Tuc analysis.
| ID | α | δ | r | μα* | μδ | rμ |
|---|---|---|---|---|---|---|
| (deg) | (deg) | (′) | (mas a−1) | (mas a−1) | (mas a−1) | |
| ω Cen | 201.70 | −47.48 | 45 | −3.26 | −6.74 | 1.0 |
| 47 Tuc | 6.02 | −72.08 | 45 | −5.25 | −2.58 | 1.0 |
| SMC | 6.02 | −72.08 | 45 | +0.51 | −1.28 | 0.5 |
| NGC 6752 | 287.72 | −59.99 | 15 | −3.16 | −4.04 | 1.0 |
| M5 | 229.64 | +2.08 | 15 | +4.08 | −9.86 | 1.0 |
| NGC 6397 | 265.17 | −53.68 | 20 | +3.24 | −17.65 | 1.0 |

Notes. G is filtered as <18, RUWE as <1.4, and σext as <0.1 mas in all cases. α and δ are the central right ascension and declination, respectively, and μα* and μδ are their associated central proper motions. The results for the SMC do not refer to the galaxy as a whole, but just to the region at the same position as 47 Tuc.
