Detailed Description

-Class: CellCorrectionAlg

Author: Michel Lefebvre
Date: 13/8/2003
Description: CellCorrectionAlg is a systemAlg that computes cell signal correction factors
- for HV effects
- for sampling fraction effects
- for global timing effects Corrected signal is obtained by multiplying the signal by the correction factors

Constructor & Destructor Documentation

CellCorrectionAlg::CellCorrectionAlg ( Event * event,

Geometry * hecGeom,

Headers * runHeader

)

The user should never need to use this contructor.

Parameters:

event A pointer in the event. Information contained in the event gets refreshed before the execute method is run

hecGeom Pointer to the singleton Geometry object

runHeader Pointer to the singleton HecRunHeader object
