ISMEAR    = 0      ! Gaussian smearing
SIGMA     = 0.01   ! smearing in eV, small sigma is required to avoid partial occupancies
ENCUT     = 450    ! energy cutoff

NBANDS    = 64     ! consistent with the ground state

ALGO      = BSE    ! BSE calculation
ANTIRES   = 0      ! Tamm-Dancoff approximation
NBANDSV   = 4      ! number of conduction bands in BSE
NBANDSO   = 4      ! number of valence bands in BSE
