Abundances originally published in absolute A(X) notation cannot be shown when the "Original" normalization is selected since no solar normalization was specified.

Values are assigned zero for thin disk and one for thick disk.

Spectral type values are assigned a number: F = 10, G = 20, K = 30, M = 40, plus the subclass digit (1-10), plus the roman numeral value * 0.01. Example. F2V = 12.05.

Note: The mean must be calculated in linear-space for accuracy, then converted to the standard dex notation in log-space. Therefore, mean values will appear slightly more positive compared to the log-space mean, see Help.
