The d-band centre comes back from the dead being the most consistent of the main electronic descriptors, due to its excellent transferability between five density functionals. The robustness previously observed for bulk is here evaluated for transition metal surfaces and if large surface states are not involved, a direct relation with the coordination number is disclosed.
