module parameters
implicit none
! floating point precision. Always use rl_kind in code
integer, parameter :: single_precision=4 ! single precision
integer, parameter :: double_precision=8 ! double precision
integer, parameter :: rl=double_precision ! global switch between
! single/double precision
! NOTE: As we still use BLAS subroutines, these need to be
! replaced as well when switching between double and
! single precision!
real(kind=rl), parameter :: Tolerance = 1.0e-15
! Output units
integer, parameter :: STDOUT = 6
integer, parameter :: STDERR = 0
! Numerical constants
real(kind=rl), parameter :: two_pi = 6.2831853071795862_rl
! Use Original (K,J,I) or Transposed (I,J,K) array
logical , parameter :: LUseO = .true.
logical , parameter :: LUseT = .true. ! .true.
