The screening parameter quoted in this paper (ω=0.15) is not the one that was actually used in the code. In order to reproduce our results, two ω values are needed: ω=0.1520.106 for Hartree-Fock and ω=0.15×2130.189 for the PBE part.

This erratum applies to all of our ωPBEh and HSE calculations published to date. We emphasize, however, that all our results obtained with this functional are reproducible using the two ω values quoted above. The validity of all our published HSE values is not affected.

Optimization of a single value of ω for a functional of the type reported in this paper will be presented elsewhere. We thank Oleg Vydrov and Artur Izmaylov for finding this error.
