Efficiencies and fake rates

ORCA_8_13_0; GtfPattern/test/TrackEfficiencyTree.cpp produces tree with all TkSimTracks and RecTracks with loose selection, plus basic track parameters, "signal event" flag for TkSimTracks and list of all associations in both directions.

Settings for SimpleTkSimTrack / SimpleRecTrackFilters used when producing the tree:

	nhitcut	ptcut	etamincut	etamaxcut	tipcut	lipcut
TkSimTrack	0	0.7	0	2.6	120	250
RecTrack	5	0.8	0	2.6	120	250

Reminder: for simulated tracks "tip" and "lip" refer to the production point.

Filter settings used for efficiency and fake rate plots starting from the tree ( EffPlot.C and ShowEfficiencies.C macros):

	RecTracks	SimTracks
		global efficiency	algorithmic efficiency	fake rate
Nr. of hits	8	0	8	0
Nr. of pixel hits	-	0	2	0
min. pT	0.8	0.9	0.9	0.7
abs(eta) - range	0 - 2.5	0 - 2.4	0 - 2.4	0 - 2.6
TIP / Rvtx	3.5	3.5	0.1	120
LIP / Zvtx	30	30	15	250
only signal	-	yes	yes	no
particle types	-	e,mu,pi,K,p	e,mu,pi,K,p	-
