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.
