    band-tune: permit narrower bandwidth
    
    Narrower bandwidth for more specific targeting of noise is useful, the
    used scale paremeter should probably be made dependent on the bandwidth
    to cancel out their interactions, for narrow bandwidth one now need to
    manually compensate by boosting scale.
