Notes. GCs information: position, metallicity, V_r was taken from Gaia-ESO (Gilmore et al. 2022; Randich et al. 2022), the astrometric information (proper motions) and parallaxes were taken from Gaia eDR3 (Gaia Collaboration 2021). We listed the selected cluster members’ lowest membership probability (MEM3D; when available) and the GC age. The last column displays the GCs origin reported by Massari et al. (2019). ^(a)Age reported by Forbes & Bridges (2010). ^(b)Age reported by De Angeli et al. (2005).
