Fig. 2


Trends of NLTE abundances with excitation potential and equivalent width, as determined from individual Fe i (filled circles for Eexc 1.2 eV and asterisks for Eexc < 1.2 eV) and Fe ii (open circles) lines, using our adopted stellar parameters. The dotted line indicates the mean Fe abundance from two ionisation stages and the shaded grey area its statistical error.
