8 /* History of cvs commits:
11 * Revision 1.49 2007/03/06 06:51:27 kharlov
12 * Calculation of cluster properties dep. on vertex posponed to TrackSegmentMaker
14 * Revision 1.48 2006/08/30 16:12:52 kharlov
15 * Reconstruction of raw data from beam test 2006 (B.Polichtchouk)
17 * Revision 1.47 2006/08/25 16:56:30 kharlov
18 * Compliance with Effective C++
20 * Revision 1.46 2006/08/01 12:20:17 cvetan
21 * 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
23 * Revision 1.45 2006/04/29 20:26:46 hristov
24 * Separate EMC and CPV calibration (Yu.Kharlov)
26 * Revision 1.44 2005/09/02 14:32:07 kharlov
27 * Calibration of raw data
29 * Revision 1.43 2005/05/28 14:19:04 schutz
30 * Compilation warnings fixed by T.P.

35 // Implementation version 1 of the clusterization algorithm

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