2 | // Create TClonesArray of zero misalignment objects for PMD | |
3 | // | |
4 | // Macro to randomly displace the 4 sectors of the PMD | |
5 | // in each plane. Each sector (to be misaligned) | |
6 | // of PMD houses the following : | |
7 | // (a) 6 modules of preshower plane | |
8 | // (b) 6 modules of veto plane | |
9 | // (c) The FEE boards on back plane of each module | |
10 | // (d) 6 modules of convertor plates | |
11 | // The clustering is done module-wise | |
12 | // The actual amount displacement will be provided | |
13 | // by the survey data and has to be converted into | |
14 | // displacement in x,y,z,theta, phi and psi | |
15 | ||
16 | ||
17 | // Now specify the path of the module to be misaligned | |
18 | // as followed in the PMD geant | |
