 GEOMETRY 
a) SSD + IST + PXL 



b) PIPE + PXL




c) hits from PXL and IST
pions are thrown within this geometry

1) hits + geometry structures


We see PXL hits and hardly IST hits (because of the colors of IST ladders)

2) picture is the same as above but w/o the detectors structures , only hits (usind dhits pxlh or dhits isth starsim command line)

We see now IST hits

d) more statistic : 100 events with 20 pions/event
Plot shows the SSD, IST and PXL hits using the g2t_ssd_hits,g2t_ist_hits,g2t_pxl_hits tables.



BFC RECONSTRUCTION
1) code from Yaping : 
/star/u/ypwang/disk02/istOfflineChain/offlineChain20130617/StRoot/
StIstClusterMaker/    
StIstFastSimMaker/            
StIstPedNoiseMaker/          
StIstRawHitMaker/              
StIstDbMaker/              
StIstHitMaker/              
StIstPerformanceAnalysisMaker/ 

2) also needs to update StRoot/StBFChain/BigFullChainn.h to include an "istFastSim" option
