Notes. σi are the uncertainties caused by the errors on the atmospheric parameters (i = Teff, log g, [Fe/H], ξ; see text) and σstat is the line-to-line scatter on the abundance divided by 
, where N is the number of lines used. The individual model-driven uncertainties are quadratically added to yield the total model-driven uncertainty σatm, which in turn is quadratically added to the statistical uncertainty to give the total uncertainty σtot.
