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