Notes. Differences are measured with the median value, MED, and the dispersion, MAD, for the N common stars with various constraints. The typical (median) [Fe/H] uncertainty listed in each catalogue for the corresponding selected stars is also given. When relevant, the slope of the linear fit on the distribution of the residuals versus [Fe/H] is provided.
