Notes. The expectation value of the extracted parameter adopted as the mean of all chosen models. Only for the metallicity, Z, did we adopt the median as the expectation value since the grid is evenly spaced. Values in parentheses give the uncertainty on the extracted parameter adopted from the standard deviation of all models.
