+// Adding systematic errors to the covariance:
+//
+// The systematic errors due to the misalignment and miscalibration are added to the covariance matrix
+// of the tracks (not to the clusters as they are dependent):
+// The parameters form AliTPCRecoParam are used AliTPCRecoParam::GetSystematicError
+// The systematic errors are expressed there in RMS - position (cm), angle (rad), curvature (1/cm)
+// The default values are 0.
+//
+// The sytematic errors are added to the covariance matrix in following places:
+//
+// 1. During fisrt itteration - AliTPCtrackerMI::FillESD
+// 2. Second iteration -
+// 2.a ITS->TPC - AliTPCtrackerMI::ReadSeeds
+// 2.b TPC->TRD - AliTPCtrackerMI::PropagateBack
+// 3. Third iteration -
+// 3.a TRD->TPC - AliTPCtrackerMI::ReadSeeds
+// 3.b TPC->ITS - AliTPCtrackerMI::RefitInward
+//
+// There are several places in the code which can be numerically debuged
+// This code is keeped in order to enable code development and to check the calibration implementtion
+//
+// 1. ErrParam stream (Log level 9) - dump information about
+// 1.a) cluster
+// 2.a) cluster error estimate
+// 3.a) cluster shape estimate
