class AliTPCCalibGlobalMisalignment: public AliTPCCorrection


AliTPCCalibGlobalMisalignment class
The class calculates the space point distortions due to simple
misalignments like shifts in caresian coordinates or a rotation
of the TPC read out planes (A and C side)
Optionaly possible to use it for visualization of the alignemnt form the Alignment OCDB
 fUseGeoManager has to be set to kTRUE to enable this option
