Selection of likely cluster member stars for the GC 47 Tuc. On the left, the vector-point diagram obtained using Gaia DR3 PMs is shown along with the distribution of stars along the ${\mu }_{\alpha }^{\ast }$ and μ_δ velocity components. The red circle represents the 2σ selection described in Sect. 2.3. The panel on the right shows the (U, U-I) and (U, C_U,B,I) CMDs for 47 Tuc obtained using ground-based photometric catalogs published by Stetson et al. (2019). Likely member stars based on the PM selection shown in the left panel are highlighted in black, while likely field interlopers are shown in gray.
