-// 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
-//
//*-- Author : Dmitri Peressounko (SUBATECH & Kurchatov Institute)
//////////////////////////////////////////////////////////////////////////////
-// Class performs digitization of Summable digits (in the PHOS case this is just
-// sum of contributions of all primary particles into give cell).
+// This TTask performs digitization of Summable digits (in the PHOS case it is just
+// the sum of contributions from all primary particles into a given cell).
// In addition it performs mixing of summable digits from different events.
-// Examples of use:
+// 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
+//
+// For each event two branches are created in TreeD:
+// "PHOS" - list of digits
+// "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization
+//
+// Note, that one can set a title for new digits branch, and repeat digitization with
+// another set of parameters.
+//
+// Use case:
// root[0] AliPHOSDigitizer * d = new AliPHOSDigitizer() ;
// root[1] d->ExecuteTask()
// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
// //Digitizes SDigitis in all events found in file galice.root
-// //Depending on variable "CONFIG_SPLIT_FILE" reads branches stored in galice.root
-// //or in PHOS.SDigits.root
-// root[2] AliPHOSDigitizer * d1 = new AliPHOSDigitizer("galice1.root") ; // Will read sdigits from galice1.root
-// root[3] d1->MixWith("galice2.root",1) // Reads another portion of sdigits from galice2.root
-// // says, that this will be output file
-// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
-// root[3] d1->MixWith("galice3.root",1) // Reads another portion of sdigits from galice3.root
-// // overwrides previous definition of output file
-// root[4] d->ExecuteTask() // Reads SDigits from files galice1.root, galice2.root ....
-// // mixes them and stores produced Digits in file galice3.root
//
+// root[2] AliPHOSDigitizer * d1 = new AliPHOSDigitizer("galice1.root") ;
+// // Will read sdigits from galice1.root
+// root[3] d1->MixWith("galice2.root")
+// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
+// // Reads another set of sdigits from galice2.root
+// root[3] d1->MixWith("galice3.root")
+// // Reads another set of sdigits from galice3.root
+// root[4] d->ExecuteTask("deb timing")
+// // Reads SDigits from files galice1.root, galice2.root ....
+// // mixes them and stores produced Digits in file galice1.root
+// // deb - prints number of produced digits
