Notes. The stars in the first section belong to the thin disk according to the α-elements criteria. The classifications of RR Lyrae stars are sourced from Clementini et al. (2023). CG Peg and DH Peg are not classified as variables and lack LC data in the Gaia RR Lyrae catalog, so their types are not reported. They are classified as RRab and RRc in Kervella et al. (2019a,b), respectively.⋆ Do not have specified types in Kervella et al. (2019a,b). Refer to 3.2 for more information on RW TrA. ⋆⋆ Different types reported in Kervella et al. (2019a,b).
