Notes. Additional details, i.e. if the star is an interloper and not a robust stream candidate (see Sect. 5.3 for an explanation and discussion on this point) or if the star is considered as a cluster member according to the RV-based membership (see Schiavon et al. 2024), are described in the third column.
