// 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
// // 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("Redestal 0.001")
+// root [3] s->SetSDigitsBranch("Pedestal 0.001")
// // and write them into the new branch
-// root [4] s->ExeciteTask("deb all tim")
+// root [4] s->ExecuteTask("deb all tim")
// // available parameters:
// deb - print # of produced SDigitis
// deb all - print # and list of produced SDigits
