19 /* History of cvs commits:
22 * Revision 1.56 2007/10/19 18:04:29 schutz
23 * The standalone QA data maker is called from AliSimulation and AliReconstruction outside the event loop; i.e. re-reading the data. The QA data making in the event loop has been commented out.
25 * Revision 1.55 2007/10/14 21:08:10 schutz
26 * Introduced the checking of QA results from previous step before entering the event loop
28 * Revision 1.54 2007/10/10 09:05:10 schutz
29 * Changing name QualAss to QA
31 * Revision 1.53 2007/09/30 17:08:20 schutz
32 * Introducing the notion of QA data acquisition cycle (needed by online)
34 * Revision 1.52 2007/09/26 14:22:18 cvetan
35 * Important changes to the reconstructor classes. Complete elimination of the run-loaders, which are now steered only from AliReconstruction. Removal of the corresponding Reconstruct() and FillESD() methods.
37 * Revision 1.51 2007/08/07 14:12:03 kharlov
38 * Quality assurance added (Yves Schutz)
40 * Revision 1.50 2006/08/28 10:01:56 kharlov
41 * Effective C++ warnings fixed (Timur Pocheptsov)
43 * Revision 1.49 2006/05/10 06:42:53 kharlov
44 * Remove redundant loop over primaries
46 * Revision 1.48 2006/04/22 10:30:17 hristov
47 * Add fEnergy to AliPHOSDigit and operate with EMC amplitude in energy units (Yu.Kharlov)
49 * Revision 1.47 2005/05/28 14:19:04 schutz
50 * Compilation warnings fixed by T.P.

55 // This is a TTask that makes SDigits out of Hits
56 // The name of the TTask is also the title of the branch that will contain
57 // the created SDigits
58 // The title of the TTAsk is the name of the file that contains the hits from
59 // which the SDigits are created
60 // A Summable Digits is the sum of all hits originating
61 // from one primary in one active cell
62 // A threshold for assignment of the primary to SDigit is applied
63 // SDigits are written to TreeS, branch "PHOS"
64 // AliPHOSSDigitizer with all current parameters is written
65 // to TreeS branch "AliPHOSSDigitizer".
66 // Both branches have the same title. If necessary one can produce
67 // another set of SDigits with different parameters. Two versions
68 // can be distunguished using titles of the branches.
