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); // | |
