SYSTEM   = C RS-DDH unoccupied states

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


LHFCALC  = .TRUE. ! exact exchange
LMODELHF = .TRUE. ! range-separated hybrid functional
HFSCREEN = 1.70   ! the range-separation parameter
AEXX     = 0.175  ! the fraction of exact exchange

NBANDS   = 8      ! include 4 valence and 4 conduction states

ALGO     = Exact  ! use exact diagonalization of the Hamiltonian
NELM     = 1      ! since we are already converged stop after one step

LOPTICS  = T      ! write WAVEDER
