PFILTER

An element for energy and momentum filtration.
Parameter Name Units Type Default Description
DELTALIMIT   double -1 maximum fractional momentum deviation
LOWERFRACTION   double 0.0 fraction of lowest-momentum particles to remove
UPPERFRACTION   double 0.0 fraction of highest-momentum particles to remove
FIXPLIMITS   long 0 fix the limits in p from LOWERFRACTION and UPPERFRACTION applied to first beam
BEAMCENTERED   long 0 if nonzero, center for DELTALIMIT is average beam momentum
