This module defines a constant-velocity NMO-transformation
of the input trace into the output trace.
It requires spat_map=trace_to_trace in the parameters.
map_amp_init = mov3d_hyper_const_init
map_amp = mov3d_hyper_const
oper_domain = none
The interface of mov3d_hyper_const_init is:
function mov3d_hyper_const_init (slow_nmo) result (stat)
real :: slow_nmo
integer :: stat
