src

IstTracking

• extract pedestal & noise
• find hit cluster
• extract position dependent tracking resolution and efficiency

FstUtil

• provide utility class for analysis
• FstRawHit: class of raw hit
• FstCluster: class of cluster
• FstTrack: class of track of raw hit and cluster
• FstEvent: class of all the information saved in one event
• FstCons: all constants used in the analysis => geometry & alignment & threshold etc.

FstClusterMaker

• identify raw hits (4.5 for FST & 6.0 for IST)
• group raw hits into clusters
• find tracking based on hits and clusters in IST1 & IST3
• save all information to FstEvent
• Thershold and number of used time bins can be adjusted as an input argument in macros/FstClusterMaker/makeFstCluster.C

FstTracking

• read in FstEvent
• generate histograms for resoluiton and efficiency

FstQAStudy

• read in FstEvent
• generate histgram for QA study
• generate Hit Maps
• generate Cluster Maps
• generate Track Hit Maps

---

macro

• IstTracking extract IST position dependent tracking resolution and efficiency.
• FstUtil test FstRawHit, FstCluster, FstTrack and FstEvent classes.
• FstClusterMaker analyze raw data and produce RawHits, Clusters and Tracks.
• FstTracking do the alignment and generate track resolution and efficiency histograms
• FstQAStudy: generate Event Display histograms
• FstPlotMacro: produce all QA plots for one specific configuration => Threshold & NumOfTimeBins

---

compile the code

• mkdir build
• cd ./build
• cmake ..
• make install
• a shared lib can be found at ${PROJECT_SOURCE_DIR}/lib

analysis work flow

1. compile the code
2. generate data list for the module and HV
3. FstClusterMaker: root -l -b -q makeFstCluster.C

• produce TTree with FstEvent
• loopAll.sh to loop over all configurations
• output file can be sepcified in the macro

4. generate cluster list for Tracking and QA
5. FstTracking

• use getAlignment_FSTClusters_3Layer.C to extract alignment parameters for each sensor

6. update alignment paramters in src/FstUtil/FstCons.h
7. re-compile the code and run FstClusterMaker with updated alignment parameters

• loopAll.sh to loop over all configurations

8. FstTracking: root -l -b -q doFstTracking.C

• produce histograms for residual and efficiency
• output file canbe sepcified in the macro
• loopAll.sh to loop over all configurations

9. FstQAStudy: root -l -b -q doFstQAStudy.C

• generate TTree for EventDisplay
• output file canbe sepcified in the macro
• loopAll.sh to loop over all configurations

10. FstPlotMacro: . ./plotQA.sh

• change hv and config in plotQA.sh for different HV and configuration
• all QA plots can be found in figures/module_hv_config
• loopAll.sh to loop over all configurations
