+ * $Log$
+ * Revision 1.56 2007/10/19 18:04:29 schutz
+ * 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.
+ *
+ * Revision 1.55 2007/10/14 21:08:10 schutz
+ * Introduced the checking of QA results from previous step before entering the event loop
+ *
+ * Revision 1.54 2007/10/10 09:05:10 schutz
+ * Changing name QualAss to QA
+ *
+ * Revision 1.53 2007/09/30 17:08:20 schutz
+ * Introducing the notion of QA data acquisition cycle (needed by online)
+ *
+ * Revision 1.52 2007/09/26 14:22:18 cvetan
+ * 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.
+ *
+ * Revision 1.51 2007/08/07 14:12:03 kharlov
+ * Quality assurance added (Yves Schutz)

-// This is a TTask that constructs SDigits out of Hits
-// A Summable Digits is the sum of all hits in a cell
-// A threshold is applied
+// This is a TTask that makes SDigits out of Hits
+// The name of the TTask is also the title of the branch that will contain
+// the created SDigits
+// The title of the TTAsk is the name of the file that contains the hits from
+// which the SDigits are created
+// A Summable Digits is the sum of all hits originating
+// from one primary in one active cell
+// A threshold for assignment of the primary to SDigit is applied
+// SDigits are written to TreeS, branch "PHOS"
+// AliPHOSSDigitizer with all current parameters is written
+// to TreeS branch "AliPHOSSDigitizer".
+// Both branches have the same title. If necessary one can produce
+// another set of SDigits with different parameters. Two versions
+// can be distunguished using titles of the branches.
+// User case:
+// root [0] AliPHOSSDigitizer * s = new AliPHOSSDigitizer("galice.root")
+// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
+// root [1] s->ExecuteTask()
+// // Makes SDigitis for all events stored in galice.root
+// root [2] s->SetPedestalParameter(0.001)
+// // One can change parameters of digitization
+// root [3] s->SetSDigitsBranch("Pedestal 0.001")
+// // and write them into the new branch
+// root [4] s->ExecuteTask("deb all tim")
+// // available parameters:
+// deb - print # of produced SDigitis
+// deb all - print # and list of produced SDigits
+// tim - print benchmarking information
