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

32 // Implementation version 1 of the clusterization algorithm

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