-// Special configurations of the HRS (e.g. more detectors, different

-//
-// 1. Use the AddDetector() method to include a new detector
-// in this apparatus. The detector will be decoded properly,
-// and its variables will be available for cuts and histograms.
-// Its processing methods will also be called by the generic Reconstruct()
-// algorithm implemented in THaSpectrometer::Reconstruct() and should
-// be correctly handled if the detector class follows the standard
-// interface design.
-//
-// 2. Write a derived class that creates the detector in the
-// constructor. Write a new Reconstruct() method or extend the existing
-// one if necessary.
-//
-// 3. Write a new class inheriting from THaSpectrometer, using this
-// class as an example. This is appropriate if your HRS
-// configuration has fewer or different detectors than the
-// standard HRS. (It might not be sensible to provide a RemoveDetector()
-// method since Reconstruct() relies on the presence of the
-// standard detectors to some extent.)

-// 'reference distance', corresponding to the pathlength correction
-// matrix.

-// with sorting ON
-//
-// if fSelUsingScin == 1 then golden track is calculetd just like
-// engine/HTRACKING/h_select_best_track_using_scin.h. This method
-// gives the best track with minimum value of chi2/ndf but with
-// additional cuts on the tracks. These cuts are on dedx, beta
-// and on energy.

+/** \class THcScalerEvtHandler
+ \ingroup Base
+
+ Event handler for Hall C scalers
+
+
+ This class does the following
+ For a particular set of event types (here, event type 0)
+ decode the scalers and put some variables into global variables.
+ The global variables can then appear in the Podd output tree T.
+ In addition, a tree "TS" is created by this class; it contains
+ just the scaler data by itself. Note, the "fName" is concatenated
+ with "TS" to ensure the tree is unqiue; further, "fName" is
+ concatenated with the name of the global variables, for uniqueness.
+ The list of global variables and how they are tied to the
+ scaler module and channels is defined here; eventually this
+ will be modified to use a scaler.map file
+ NOTE: if you don't have the scaler map file (e.g. Leftscalevt.map)
+ there will be no variable output to the Trees.
+
+ To use in the analyzer, your setup script needs something like this
+ gHaEvtHandlers->Add (new THcScalerEvtHandler("HMS","HC scaler event type 0"));
+
+ To enable debugging you may try this in the setup script
+
+ THcScalerEvtHandler *hscaler = new THcScalerEvtHandler("HS","HC scaler event type 0");
+ hscaler->SetDebugFile("HScaler.txt");
+ gHaEvtHandlers->Add (hscaler);
