4 This directory contains a set of scripts related to PHOS alignment.
6 The PHOS alignment object (AliPHOSAlignData) contans as data members 3
9 center position of each module in MARS
10 module orientation in MARS
12 The script AliPHOSSetAlignment.C allows to set PHOS align object for
14 1) PHOS geometry for the first LHC run 2007, one module with ideal
16 2) Full PHOS geometry with all 5 modules randomly displaced.
17 The align object is being written to CBD to the local directory
18 InitAlignDB/PHOS/Alignment/Geometry for the case 1 and directory
19 DisAlignDB/PHOS/Alignment/Geometry for the case 2.
20 This script uses a menu (TControlBar) to set and read the align
23 The script AliPHOSDisalign.C runs simulations described in Config.C
24 (100 electrons towards the PHOS apperture, all detectors but PHOS are
25 switched off). Before running simulations, the PHOS align object is
26 read from the CDB. The first argument of the function AliPHOSDisalign
27 sets the upper level directory name containing the CBD object.
29 When the disaligned PHOS geometry was created, one has to check it for
31 gGeoManager->CheckOverlaps(0.1);
32 gGeoManager->PrintOverlaps();
