VESPA autocorrelator.

VESPA allows many different resolutions and bandwidths, depending on
the "mode" used. For details see the VESPA user's guide.

NOTE: VESPA should NORMALLY be used with receivers in /WIDTH NARROW
mode.  As a special setup VESPA can also be used with receivers in
/WIDTH WIDE mode, but then only in the lower half of the receiver
bandwidth!  In this case, fShift must be set so that the VESPA band
falls within the lower half of the "WIDE" receiver bandwidth.  paKo
will give an appropriate Error message if the fShift is not adequate.
The complete rules for this are very complex -- if in doubt, consult
an expert, e.g., G.P.!
