Notes. Columns are as follows: (1) Cluster name. (2) Number of available BSSs in the literature with available astrophysical parameters. (3) Mean of the effective BSS temperature provided. (4) Mean of the decadal logarithm of the BSS surface gravity. (5) Mean of the BSS stellar mass. (6) Reference. For data provided by Jadhav & Subramaniam (2021, or JS21), we considered stars labeled BSS and pBSS (probable BSS).
