Notes. Column (1) lists the main and alternate cluster ID. Column (2) is the number of cluster members used in determining the ⟨W′⟩ values given in Col. (3). Column (4) gives the source of the ⟨W′⟩ values: 1 for direct G09 measurements, 2 for transformed AD91 measurements and 3 for the average of both measurement techniques. Column (5) is the standard deviation of the ⟨W′⟩ values. Column (6) is the [Fe/H] on the C09 scale which results from applying the abundance calibration. Column (7) is the total uncertainty in the [Fe/H] value: the rms sum of the abundance uncertainties from the standard error of the mean in ⟨W′⟩, from the calibration uncertainty, and from the effects of differential reddening where necessary. Columns (8) and (9) are the H10 abundance and weight while Cols. (10) and (11) are the abundance and error from Appendix 1 of C09 (clusters with a “1” in the Notes column only). Column (12) indicates if the effects of differential reddening are significant, details are given in the appropriate sub-section for these clusters. Column (13) gives the ratio of the rms dispersion around the linear fit with fixed slope, to the mean measurement error. In the last column we mark candidate clusters for metallicity dispersion with a solid arrow head, while marginal candidates are marked with an open arrow head.
