Notes. Taken mainly from the SAGA database, Suda et al. (2008). The stars are classified as MS if Teff> 5500 K and log g ≥ 3.25 and as RGB otherwise.
The evolutionary status of 53327-2044-515 is uncertain so that the average abundances of dwarf and subgiant solutions are taken, as done in Norris et al. (2013).
