0004 # with the track direction. If this fraction is high (>0.4) the
0005 # event is declared to be a PKAM.
0006 # Starting in CMSSW_3_6_0_pre3 pixel hits with low probability
0007 # are removed from tracks in the outlier rejection. To make
0008 # sure that this filter still works, one has to turn this feature
