// To print statistics after processing use:
// fPhysicsSelection->Print();
//
+// To seleect the BX ids corresponding to real bunches crossings p2 use:
+// fPhysicsSelection->SetUseBXNumbers();
+// you cannot process runs with different filling schemes if you require this option.
+//
+// To compute the Background automatically using the control triggers
+// use:
+// fPhysicsSelection->SetComputeBG();
+// this will show the value of the Beam Gas, accidentals and good
+// events as additional rows in the statistic tables, but it will NOT
+// subtract the background automatically.
+// This option will only work for runs taken with the CINT1
+// suite. This options enables automatically also the usage of BX
+// numbers. You can only process one run at a time if you require this
+// options, because it uses the bunch intensity estimated run by run.
+//
+// The BG will usually be more important in the so-called "bin 0": the
+// class can also compute the statistics table for events in this
+// bin. Since the definition of bin 0 may in general change from
+// analysis to analysis, the user needs to provide a callback
+// implementing the definition of bin zero. The callback should be
+// implemented as a method in the analysis task and should override
+// the IsEventInBinZero method of AliAnalysisTaskSE, and should thus
+// have the the following prototype:
+// Bool_t IsEventInBinZero();
+// It should return true if the event is in the bin 0 and it is set by
+// passing to the physics selection the NAME of the task where the
+// callback is implemented:
+// fPhysicsSelection->SetBin0Callback("MyTask").
+//
+//
// Usually the class selects the trigger scheme by itself depending on the run number.
// Nevertheless, you can do that manually by calling AddCollisionTriggerClass() and AddBGTriggerClass()
// Example:
// to be present:
// AddBGTriggerClass("+CSMBA-ABCE-NOPF-ALL -CSMBB-ABCE-NOPF-ALL");
