BACKEND /PERCENTAGE

        /PERCENTAGE percentage

        Real :: percentage  !  percentage of bandwidth to use

        This is a special option for the autocorrelators, VESPA and WILMA.

        For autocorrelators normally some channels at both ends of the band
        are blanked because they do not contain usable data, and only the
        central 'percentage' of the "theoretical" bandwidth is used, typically
        about 90%.  Reasonable conservative defaults are automatically
        applied: in general 90%, but 82% for VESPA with bandwidth 640.  This
        option allows the observer to adjust the percentage for special
        purposes.

        For WILMA connected to EMIR, the useful bandwidth is 3720 MHz,
        and counted as 100%.

        See VESPA user's guide for details.
