17 TPC Kalman filter implementation for TPC sector alignment.
18 Output of the AliTPCcalibAlign is used as a input for TPC global alignment.
19 In AliTPCcalibAlign histograms - track parameter matching at sector boundaries are created.
20 Each sector is aligned with 5 neighborhoud (sectors)
21 1. Up-down - 1
22 2. Left-right - 4
23
24 Sector alignment parameters are obtained finding the alignment parameters, minimizing
25 misalignmnet for all piars fo sectors.
26
27 Global minimization- MakeGlobalAlign

30 Example usage:
31 gSystem->Load("libANALYSIS");
32 gSystem->Load("libTPCcalib");

125d3a38 37
38 AliTPCkalmanAlign kalmanAlign("TPC align", "TPC align"); // create the object
39 kalmanAlign.ReadAlign("CalibObjects.root"); // read the calibration form file
40 kalmanAlign.MakeGlobalAlign(); // do kalman alignment
