Notes.KAGBB, KRC, and KRGBB are the K-band peaks obtained for the Gaussian fits of the LF. is the relative fraction of RGBB stars of that in RC stars. ΔRGBB − RC is the distance between the peaks KRGBB − KRC. The uncertainties that are not specified in the table are ΔKAGBB = ±0.05, ΔKRC = ±0.05, ΔKRGBB = ±0.05, Δ(J − K)RC = 0.01, and Δ(J − K)RGBB = 0.01. Accounting for atomic diffusion would reduce the age of the models ∼0.7 − 1 Gyr (see main text).
