  • Had to modify the calculation of the full non-local ladder vertex due to an error in the derivation in my master's thesis. Should be fixed in this run.
  • Also found out that the calculation of the local diagrams via B.26 does not work, since there is no orbital transformation that connects \Gamma to \tilde\Gamma. Now done with a new approach.
  • Also messed up a sign in the local diagrams when subtracting the F_loc_ud component.
