A comprehensible textual description of what actually is done in the procude
is still missing.

User documentation
------------------
The theory behind the Fourier domain least squares engine is outlined by
Lisa Groos (2013, Appendix F, page 146). She also give a description of a
procedure to find an approrpiate value for the water level, by application of
the L-curve criterion (Groos, 2013, Appendix G, page 148).

Fourier domain least squares procedure
======================================
Detailed description
--------------------
This engine calculates a least squares fit in the Fourier
domain. A waterlevel as a fraction of the signal energy of the
input synthetics is applied. If per receiver scaling is
selected, the receivers will be weighted in the deconvolution.
Procedure: Least squares in the frequency domain
------------------------------------------------
This procedure calculates a least squares fit in the Fourier domain. A
waterlevel as a fraction of the signal energy of the input synthetics is
applied. If per receiver scaling is selected, the receivers will be weighted
in the deconvolution.
Options and parameters:
waterlevel=l waterlevel to be applied for regularization.
waterlevel=l waterlevel to be applied for regularization.
