PXL slow simulation chain

Updated on Tue, 2013-10-29 08:53. Originally created by bouchet on 2013-05-11 12:08.
The slow simulation chain is composed (in order) by :
  • StPxlDigMapsMaker : gives a list of fired pixels per sensor
  • StPxlClusterMaker   : gives a list of reconstructed clusters per sensor
  • StPxlHitMaker         : gives a list of hits (StPxlHit) and write them to StEvent
A) test of StPxlClusterMaker : cluster splitting
2 samples are used :
  1. tracks with Pt =0.5GeV/c
  2. tracks with Pt= 5 GeV/c
a) Pt =0.5 GeV/c

The CluserMaker then finds the following clusters :

16 pixels splitted into 2 clusters
 

12 pixels --> 1 cluster


b) Pt = 5GeV/c
