Iron abundances as a function of the pulsation phase, effective temperature, and equivalent width for lines excluded from the initial line list. These examples, for HARPS (green circles), FEROS (blue triangle), and STELLA (red stars) spectra of β Dor and ζ Gem, show a dependence of the abundances on the equivalent widths possibly caused by blends. Lines too weak or too strong (probably saturated) are represented by light gray symbols. The hatched regions around the dashed lines indicate the 1-σ uncertainty around the mean.
