Influence of model atmosphere choice on obtained abundances. Top panel: predicted difference in Fe abundance computed with STAGGER and CO5BOLD model atmospheres as a function of lower level excitation potential for Fe I lines. Bottom panel: predicted difference in Ca abundance computed with STAGGER and CO5BOLD model atmospheres as a function of difference in lower level excitation potential for Ca I lines. See Sect. 2.3 for details.
