c FOR EACH POSSIBLE CONSTIUENT, these parameters are given:
c alpha = correction factor for first order load tides
c amp = amplitude of equilibrium tide in m
c ph = Currently set to zero ... phases for
c each constituent are referred to the time
c when the phase of the forcing for that
c constituent is zero on the Greenich meridian.)

c omega = angular frequency of constituent, in radians
real alpha_d(ncmx),ph_d(ncmx),amp_d(ncmx),omega_d(ncmx)

• ,phase_mkB(ncmx),beta_SE(ncmx)
integer ispec_d(ncmx)

c I am putting 0 for ms2,mn4 etc. for now: correct later
c Now this correction is done using the SAL file (h_TPXO3_90-90.load)
c I replace beta_SE with units for now (on case we decide to switch back
c to old version) and comment the old numbers - this way I do NOT change
c anything in subroutines
c This was in weights.h before - placed here not to mix with w!
c to remove solid Earth tide multily by beta:
