# NOTE: This filter counts the number of pixel hits incompatible
# with the track direction. If this fraction is high (>0.4) the
# event is declared to be a PKAM.
# Starting in CMSSW_3_6_0_pre3 pixel hits with low probability
# are removed from tracks in the outlier rejection. To make
# sure that this filter still works, one has to turn this feature
# OFF here:
# http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/CMSSW/TrackingTools/TrackFitters/python/RungeKuttaFitters_cff.py
# by changing:
# LogPixelProbabilityCut = cms.double(-14.0), 
# to:
# LogPixelProbabilityCut = cms.double(-16.0),
