Function Documentation

void AliTPCCorrectionDemo

(

)

This is a Demo function of the general class AliTPCCorrection, which is used for general space point correction due to different effects. The effects used in this Demo are:

1. ExB twist - general offset of the TPC axis in comparison to the B field axis
2. GG error (Gating Grid volt. error) - not perfectly aligned GG voltage (in terms of voltage)
3. ExBBShape - B field shape correction of the secound order

See class descriptions for further details
