Photospheric abundances of the most heavy elements in our stratified models for G191−B2B (top panel) and RE 0503−289 (bottom panel). IG denotes a generic atom (including Ca, Sc, Ti, V, Cr, Mn, and Co). The respective solar abundances are indicated on the left and right side of the panels. The value for Tc is a typical abundance measured in red giants (see text).
