18// //
19// An AliTRDalignment object contains the alignment data (3 shifts and 3 //
20// tilts) for all the alignable volumes of the TRD, i.e. for 18 supermodules //
21// and 540 chambers. The class provides simple tools for reading and writing //
22// these data in different formats, and for generating fake data that can be //
23// used to simulate misalignment. //
24// The six alignment variables have the following meaning: //
25// shift in rphi //
26// shift in z //
27// shift in r //
28// tilt around rphi //
29// tilt around z //
30// tilt around r //
31// The shifts are in cm and the tilts are in degrees. //
32// The currently supported formats are: //
33// - ascii //
34// - root file containing a TClonesArray of alignment objects //
35// - offline conditions database //
36// - OCDB-like root file //
37// - geometry file (like misaligned_geometry.root) //
38// //
69219822 39// Some examples of usage (in an aliroot session): //
40// AliTRDalignment a,b,c,d,e; //
41// double xsm[]={0,0,0,-70,0,0}; //
42// double xch[]={0,0,-50,0,0,0}; //
43// a.SetSm(4,xsm); //
44// a.SetCh(120,xch); //
45// a.WriteAscii("kuku.dat"); //
46// TGeoManager::Import("geometry.root"); a.WriteRoot("kuku.root"); //
47// TGeoManager::Import("geometry.root"); a.WriteDB("kukudb.root",0,0); //
48// TGeoManager::Import("geometry.root"); //
49// a.WriteDB("local://$ALICE_ROOT", "TRD/Align/Data", 0,0); //
