Comparison of normalized ages derived from different sets of models in the CG-metallicity scale. The difference between normalized ages derived using P04, B94, and G00 models, respectively, and the D07 models are shown. It can be seen that relative ages derived using the MS fitting method are independent of the adopted model.
