We thank K. Hinkle and T. Lebzelter for helping us to access the FTS data of several red giants and J. Hron for valuable suggestions. Part of this work was supported by the Austrian Science Fund Project S7308-AST. The necessary computing facilities were made available through support from the Carlsberg Foundation. We acknowledge travel support from the Danish Natural Science Research Council.
