15 * Quality assurance added (Yves Schutz)
17 * Revision 1.51 2007/04/11 11:55:45 policheh
18 * SetDistancesToBadChannels() added.
20 * Revision 1.50 2007/03/28 19:18:15 kharlov
21 * RecPoints recalculation in TSM removed
23 * Revision 1.49 2007/03/06 06:51:27 kharlov
24 * Calculation of cluster properties dep. on vertex posponed to TrackSegmentMaker
26 * Revision 1.48 2006/08/30 16:12:52 kharlov
27 * Reconstruction of raw data from beam test 2006 (B.Polichtchouk)
29 * Revision 1.47 2006/08/25 16:56:30 kharlov
30 * Compliance with Effective C++
32 * Revision 1.46 2006/08/01 12:20:17 cvetan
33 * 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
35 * Revision 1.45 2006/04/29 20:26:46 hristov
36 * Separate EMC and CPV calibration (Yu.Kharlov)
38 * Revision 1.44 2005/09/02 14:32:07 kharlov
39 * Calibration of raw data
41 * Revision 1.43 2005/05/28 14:19:04 schutz
42 * Compilation warnings fixed by T.P.
