P-tensors (in eV) for a 〈100〉-split dumbbell self-interstitial and a vacancy in Ag and Cu at both the ground-state and saddle point configurations. The ground-state interstitial is oriented in the [100] direction. Its saddle point configuration is for a [100]-to-[010] migration path (see Methods for details). The vacancy saddle point is for migration along the [110] direction.
