NAME

Fx2d - 2D FX decon


SYNOPSIS

 Fx2d < in.H > out.H


INPUT PARAMETERS

w1,w2 - integer
      window sizes in samples to calculate the
      noise filters in.  The noise and signal should
      be stationary within these windows.
k1,k2 - integer
      number of windows in each direction
noper - integer
      PEF (prediction error filter) size.
lambda - real
      stabilization factor


COMMENTS

     default   w1=20, w2=10
               noper=5  -  5 is generally good, less than 4 may produce
                           poor answers, more than 7 wastes time, and the
                           results are generally insensitive to values
                           between 5 and 7.
               k1 = 1.5 * n1/(w1+1.)
               k2 = 1.5 * n2/(w2-noper+1.)
               lambda = 0.0  -- real data generally has enough noise
                                to keep the process stable.  Synthetic
                                data may need a small lambda, say 0.001.
