Notes. Here, we list the calculated absolute visual magnitude, metallicity, calculated luminosity, mean effective temperature, the standard deviation (σ) of the effective temperature, mass, metallicity Z, the absolute ages and the reference ages. The reference age is the age at the defined turn-around point of the evolutionary tracks.
