   # GW calculation of Toluene. By default, the highest occupied and lowest
   # unoccupied state are calculated. We use an all-electron basis set 
   # since core-correlation effects are important to capture all screening effects.

   # Since we are interested in an accurate QP HOMO-LUMO gap, we use the aug-TZ2P 
   # basis set. To ensure numerical stability, we switch on the dependency key.

   # We also use imaginary time and imaginary frequency grids of 16 points each.
   # Note, that PBE is not a recommended starting point (better hybrid PBE0).
   # Also note, that Good fitsetQuality is recommended
