04236e67 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.
24 *
c65c502a 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
27 *
8661738e 28 * Revision 1.54 2007/10/10 09:05:10 schutz
29 * Changing name QualAss to QA
30 *
b8274834 31 * Revision 1.53 2007/09/30 17:08:20 schutz
32 * Introducing the notion of QA data acquisition cycle (needed by online)
33 *
5b188f2f 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.

7acf6008 42// This is a TTask that makes SDigits out of Hits
7b7c1533 43// The name of the TTask is also the title of the branch that will contain
44// the created SDigits
45// The title of the TTAsk is the name of the file that contains the hits from
46// which the SDigits are created
7acf6008 47// A Summable Digits is the sum of all hits originating
48// from one primary in one active cell
49// A threshold for assignment of the primary to SDigit is applied
50// SDigits are written to TreeS, branch "PHOS"
51// AliPHOSSDigitizer with all current parameters is written
52// to TreeS branch "AliPHOSSDigitizer".
f035f6ce 53// Both branches have the same title. If necessary one can produce
54// another set of SDigits with different parameters. Two versions
55// can be distunguished using titles of the branches.
56// User case:
a4e98857 57// root [0] AliPHOSSDigitizer * s = new AliPHOSSDigitizer("galice.root")
58// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
f21fc003 59// root [1] s->Digitize()
f035f6ce 60// // Makes SDigitis for all events stored in galice.root
a4e98857 61// root [2] s->SetPedestalParameter(0.001)
f035f6ce 62// // One can change parameters of digitization
3de072dc 63// root [3] s->SetSDigitsBranch("Pedestal 0.001")
f035f6ce 64// // and write them into the new branch
3de072dc 65// root [4] s->ExecuteTask("deb all tim")
f035f6ce 66// // available parameters:
67// deb - print # of produced SDigitis
68// deb all - print # and list of produced SDigits
69// tim - print benchmarking information
