19// Class to make a internal alignemnt of TPC chambers //
20//
967eae0d 21// Requierements - Warnings:
22// 1. Before using this componenent the magnetic filed has to be set properly //
1c1a1176 23// 2. The systematic effects - unlinearities has to be understood
967eae0d 24//
1c1a1176 25// If systematic and unlinearities are not under control
26// the alignment is just effective alignment. Not second order corrction
27// are calculated.
28//
29// The histograming of the edge effects and unlineratities integral part
30// of the component (currently only in debug stream)
31//
32// 3 general type of linear transformation investigated (see bellow)
33//
34// By default only 6 parameter alignment to be used - other just for QA purposes
f8a2dcfb 35
1c1a1176 36// Different linear tranformation investigated
972cf6f2 37// 12 parameters - arbitrary linear transformation

53// Debug stream supported
54// 0. Align - The main output of the Alignment component
55// - Used for visualization of the misalignment between sectors
56// - Results of the missalignment fit and the mean and sigmas of histograms
57// stored there
58// 1. Tracklet - StreamLevel >1
59// - Dump all information about tracklet match from sector1 to sector 2
60// - Default histogram residulas created in parallel
61// - Check this streamer in case of suspicious content of these histograms
62// 2. Track - StreamLevel>5
63// - For debugging of the edge effects
64// - All information - extrapolation inside of one sectors
65// - Created in order to distinguish between unlinearities inside of o
66// sector and missalignment
