11 * Revision 1.47 2006/08/25 16:56:30 kharlov
12 * Compliance with Effective C++
14 * Revision 1.46 2006/08/01 12:20:17 cvetan
15 * 1. Adding a possibility to read and reconstruct an old rcu formatted raw data. This is controlled by an option of AliReconstruction and AliPHOSReconstructor. 2. In case of raw data processing (without galice.root) create the default AliPHOSGeometry object. Most likely this should be moved to the CDB
17 * Revision 1.45 2006/04/29 20:26:46 hristov
18 * Separate EMC and CPV calibration (Yu.Kharlov)
20 * Revision 1.44 2005/09/02 14:32:07 kharlov
21 * Calibration of raw data
23 * Revision 1.43 2005/05/28 14:19:04 schutz
24 * Compilation warnings fixed by T.P.

29 // Implementation version 1 of the clusterization algorithm

31 // unfolding of the clusters with several local maxima.
32 // results are stored in TreeR#, branches PHOSEmcRP (EMC recPoints),
33 // PHOSCpvRP (CPV RecPoints) and AliPHOSClusterizer
