NCRPA_BANDS = [integer array]
Description: Controls which bands are excluded in the constrained random-phase approximation. Check also NTARGET_STATES.
This tag is effective for ALGO = CRPA and ignored otherwise.
For instance
NCRPA_BANDS = 21 22 23
removes all screening effects between bands 21, 22 and 23 from the constrained random-phase approximation of the screened Coulomb interaction.
