integer, intent(in) :: ndir     ! number of directions
integer, intent(in) :: nsig     ! number of sigma values in array
integer, intent(in) :: iquad    ! method of computing nonlinear quadruplet interactions
!
real, intent(in)    :: aquad(nsig,ndir)        ! action density spectrum as a function of (sigma,dir)
real, intent(in)    :: sigma(nsig)             ! Intrinsic frequencies
real, intent(in)    :: dir(ndir)               ! directions in radians 
real, intent(in)    :: depth                   ! local depth 
!
!
integer, intent(out):: ierr                    ! Error indicator. If no errors are detected IERR=0
!
real, intent(out)   :: xnl(nsig,ndir)          ! transfer rate dA/dt(sigma,dir)
real, intent(out)   :: diag(nsig,ndir)         ! diagonal term (dXnl/dA)

!
!     An error message is produced within the QUAD system.
!     If no errors are detected ierror = 0 
!     1, incorrect iquad
