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