This work represents an improvement over previous studies thanks to the very high spectral resolution available (R = 118 000) and to the new information on wavelengths and atomic structure of Hg II and Pt II.3 pages, no figure, to appear in: Proc. of the 26th workshop of the European Working Group on CP stars, eds.
