Comparison of a synthetic spectrum computed by us with Ads for the atmospheric parameters and elemental abundances derived by Hunter et al. (2009, red line) and the Flames/Giraffe observation (black line) for the star NGC 6611-006. Displayed are spectral regions with important features for the analysis, as indicated. The sharp Hα emission feature is of nebular origin. This is an example of one of the best matches between theory and observation found within our re-investigation of the sub-sample of stars drawn from the Hunter et al. (2009) work.
