Notes. The expectation value of the extracted parameters adopted as the mean of all chosen models. Only for the metallicity, Z, we adopted the median as the expectation value since the grid is evenly spaced. Values in parentheses give the uncertainties on the extracted parameters adopted from the standard deviation of all models. Parameters that agree with the model are given in bold.
