jector Augmented Wave pseudopotentials and valence electrons were represented by plane waves with a kinetic energy cutoff of 450 eV. The calculated lattice parameters for the metals show good agreement with experimental values. Metal surfaces were modeled by four-layer slabs, where the two uppermost layers were fully relaxed and the bottom ones were fixed to the bulk distances. We selected the (111) surface for the fcc metals and the (0001) for the hcp ones. Samples of the FG-dataset have been generated
