changes to the code

a) StMcEvent/StMcPixelHit.cc

 for the decoding of layer and ladder when reading the g2t table
StMcPixelHit::layer() const
{
  // 3 modules of 11 ladders each; 8 outer and 3 inner ladder per module
  // layer 1 : ladder 1 -  9
  // layer 2 : ladder 1 - 24
  // layer 1 : ladder 1 -  10 JB
  // layer 2 : ladder 1 - 30  JB
  unsigned long iLayer  = mVolumeId/1000000;
   return iLayer;
}

unsigned long
StMcPixelHit::ladder() const
{
  // 3 modules of 11 ladders each; 8 outer and 3 inner ladder per module
  // layer 1 : ladder 1 -  9
  // layer 2 : ladder 1 - 24
  // layer 1 : ladder 1 -  10 JB
  // layer 2 : ladder 1 - 30  JB
  unsigned long iLadder = (mVolumeId%1000000)/10000;
  return iLadder;
}

b) StMcEvent/StMcIstHit.cc

//jb : 1<= Module <= 24
//      1<= ladder <= 12
unsigned long
StMcIstHit::layer() const
{   
  unsigned long iLayer = mVolumeId/1000000;
  unsigned long layer;
  layer = iLayer -1;
  return layer;
}

unsigned long
StMcIstHit::ladder() const
{
  unsigned long iModule = (mVolumeId%1000000)/10000;
   return iModule-1;
}

c) StMcEvent/StMcIstHitCollection.h

  //enum { mNumberOfLayers = 3 };
  //jb layer means ladder for upgr15  :only one layer
    enum { mNumberOfLayers = 24 };
    StMcIstLayerHitCollection mLayers[mNumberOfLayers];
    ClassDef(StMcIstHitCollection,1)
};

d) IST hit issue 

I compared the ZGlobal and ZLocal of hits, with the Zposition of wafers from which they supposed to belong.

The Zposition of wafers comes from :

 

double angle    = detector->getPlacement()->getNormalRefAngle();

double radius   = detector->getPlacement()->getNormalRadius();

double zcenter  = detector->getPlacement()->getZcenter();

The position of hits come from :

pos[2] = hit->position().z(); (GLOBAL)

localpos[0]=0;

localpos[1]=0;

localpos[2]=0;

gGeoManager->GetCurrentMatrix()->MasterToLocal(pos,localpos); (LOCAL)

 

e) Results for fews hits (The hits taken in tracking are only those for wafer = 9)
