+# L1Trigger-TrackFindingTracklet
+
+This repository contains various data files that are needed to run the L1 tracking. 
+
+*** WIRING ***
+
+These contain the detailed wiring of the various modules for the "hourglass" phi sector definition, 
+for either the baseline tracking (wires_hourglass.dat) or the extended tracking that includes displaced 
+(triplet) seeding (wires_hourglassExtended.dat)
+
+wires_hourglass.dat 
+wires_hourglassExtended.dat 
+
+*** PROCESSING MODULES *** 
+
+These contain the detailed list of processing modules used for the baseline or extended tracking (e.g. VMRouter, TrackletEngine, TrackletCalculator, ...) 
+
+processingmodules_hourglass.dat
+processingmodules_hourglassExtended.dat
+
+*** MEMORY MODULES *** 
+
+These similarly contain the detailed memory modules (e.g. InputLink, AllStubs, FullMatch, TrackletParameters, ...)
+
+memorymodules_hourglass.dat
+memorymodules_hourglassExtended.dat
+
+*** LUTs FOR EXTENDED TRACKING *** 
+
+These contain LUTs needed for the extended tracking (that allows specifically reconstructing displaced trajectories). 
+
+table_TED/ => tracklet engine displaced
+table_TRE/ => triplet engine
+
+*** CHI2 FIT ***
+
+This contains track derivatives used for the chi2-based track fitting. 
+
+fitpattern.txt
+
+*** MODULES & CABLING *** 
+
+This contains information about the modules and the links that they are associated with from the DTC.
