7acf6008 20// This is a TTask that makes SDigits out of Hits
7b7c1533 21// The name of the TTask is also the title of the branch that will contain
22// the created SDigits
23// The title of the TTAsk is the name of the file that contains the hits from
24// which the SDigits are created
7acf6008 25// A Summable Digits is the sum of all hits originating
26// from one primary in one active cell
27// A threshold for assignment of the primary to SDigit is applied
28// SDigits are written to TreeS, branch "PHOS"
29// AliPHOSSDigitizer with all current parameters is written
30// to TreeS branch "AliPHOSSDigitizer".
f035f6ce 31// Both branches have the same title. If necessary one can produce
32// another set of SDigits with different parameters. Two versions
33// can be distunguished using titles of the branches.
34// User case:
a4e98857 35// root [0] AliPHOSSDigitizer * s = new AliPHOSSDigitizer("galice.root")
36// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
37// root [1] s->ExecuteTask()
f035f6ce 38// // Makes SDigitis for all events stored in galice.root
a4e98857 39// root [2] s->SetPedestalParameter(0.001)
f035f6ce 40// // One can change parameters of digitization
3de072dc 41// root [3] s->SetSDigitsBranch("Pedestal 0.001")
f035f6ce 42// // and write them into the new branch
3de072dc 43// root [4] s->ExecuteTask("deb all tim")
f035f6ce 44// // available parameters:
45// deb - print # of produced SDigitis
46// deb all - print # and list of produced SDigits
47// tim - print benchmarking information
