Notes. Star IDs are taken from Piatti et al. (2004) for NGC 2324, from WEBDA for NGC 2477, and from Prisinzano et al. (2004) for NGC 3960. The atmospheric parameters and radial velocities are from Bragaglia et al. (2008) for NGC 2324 and NGC 2477, and from Sestito et al. (2006) for NGC 3960 (also adopted by Bragaglia et al. 2008). v sin i values were derived in this work.
