Detailed Description

Class to simulate PXL hits from Monte Carlo.

This class has the responsibility to create StPxlHit objects and store them in StPxlHitCollection.

StPxlHit is a Gaussian smeared StMcPxlHit. The smearing parameters are fetched from Calibrations/tracker/PixelHitError*

This class conforms to the STAR StMaker standards.

Member Function Documentation

Int_t StPxlFastSim::addPxlHits ( const StMcPxlHitCollection &  mcPxlHitCol,
StPxlHitCollection &  pxlHitCol 
)
virtual

creates an StPxlHit object for every StMcPxlHit, and fills the hit StPxlHitCollection container.

Returns: kStOk: if hits have been loaded to StPxlHitCollection successfully.

Reimplemented from StPxlISim.

Int_t StPxlFastSim::initRun ( const TDataSet &  calib_db,
const TObjectSet *  pxlDbDataSet,
const Int_t  run 
)
virtual

A random seed is passed to mRandom PXL smearing resolutions (PixelHitError) are fetched from calib_db.

returns kStOk if resolutions have been fetched successfully. kStErr otherwise.

Implements StPxlISim.
