Yes, this is because of time inversion. F. Tran

We have done calculations on a supercell in which we substituted an impurity atom for a pristine atom. The symmetry of crystal is P1 (identity only) according to Wien2k. We used a k-points grid 18x9x5 (=810 k-points) but the number of k-points used during SCF is 405. Is there an additional symmetry element that accounts for this reduction (e.g. time inversion)? Thank you for your answer.
