/* History of cvs commits:
*
* $Log$
- * Revision 1.104 2006/11/23 13:40:44 hristov
- * Common class for raw data reading and ALTRO mappiing for PHOS and EMCAL (Gustavo, Cvetan)
+ * Revision 1.116 2007/10/10 09:05:10 schutz
+ * Changing name QualAss to QA
*
- * Revision 1.103 2006/11/14 17:11:15 hristov
- * Removing inheritances from TAttLine, TAttMarker and AliRndm in AliModule. The copy constructor and assignment operators are moved to the private part of the class and not implemented. The corresponding changes are propagated to the detectors
+ * Revision 1.115 2007/08/22 09:20:50 hristov
+ * Updated QA classes (Yves)
*
- * Revision 1.102 2006/10/27 17:14:27 kharlov
- * Introduce AliDebug and AliLog (B.Polichtchouk)
+ * Revision 1.114 2007/08/07 14:12:03 kharlov
+ * Quality assurance added (Yves Schutz)
*
- * Revision 1.101 2006/10/13 06:47:29 kharlov
- * Simulation of RAW data applies real mapping (B.Polichtchouk)
+ * Revision 1.113 2007/07/18 16:29:54 policheh
+ * Raw Sdigits energy converted to GeV.
*
- * Revision 1.100 2006/08/11 12:36:26 cvetan
- * Update of the PHOS code needed in order to read and reconstruct the beam test raw data (i.e. without an existing galice.root)
+ * Revision 1.112 2007/02/25 22:59:13 policheh
+ * Digits2Raw(): ALTRO buffer and mapping created per each DDL.
*
- * Revision 1.99 2006/06/28 11:36:09 cvetan
- * New detector numbering scheme (common for DAQ/HLT/Offline). All the subdetectors shall use the AliDAQ class for the sim and rec of the raw data. The AliDAQ and raw reader classes now provide all the necessary interfaces to write and select the detector specific raw-data payload. Look into the AliDAQ.h and AliRawReader.h for more details.
+ * Revision 1.111 2007/02/18 15:21:47 kharlov
+ * Corrections for memory leak in Digits2Raw due to AliAltroMapping
*
- * Revision 1.98 2006/05/11 11:30:48 cvetan
- * Major changes in AliAltroBuffer. Now it can be used only for writing of raw data. All the corresponding read method are removed. It is based now on AliFstream in order to avoid endianess problems. The altro raw data is written always with little endian
+ * Revision 1.110 2007/02/13 10:52:08 policheh
+ * Raw2SDigits() implemented
*
- * Revision 1.97 2006/04/22 10:30:17 hristov

+ * Removing warnings on Solaris x86
*
- * Revision 1.95 2006/03/14 19:40:41 kharlov
- * Remove De-digitizing of raw data and digitizing the raw data fit
+ * Revision 1.107 2007/01/29 16:29:37 kharlov
+ * Digits2Raw(): special workaround for digits with time out of range
*
- * Revision 1.94 2006/03/07 18:56:25 kharlov
- * CDB is passed via environment variable
- *
- * Revision 1.93 2005/11/22 08:45:11 kharlov
- * Calibration is read from CDB if any (Boris Polichtchouk)
- *
- * Revision 1.92 2005/11/03 13:09:19 hristov

- * Mixture ArCO2 is corrected
- *
- * Revision 1.90 2005/06/17 07:39:07 hristov
