How to use ClusterSummary class:

ClusterSummary provides summary inforation for a number of cluster dependent variables.
All the variables are stored within variables_
The modules selected are stored within modules_
The number of variables for each module is stored within iterator_

[If putting ClusterSummary into producer]

1) In beginJob() of Producer, set the method   

  Cluster.SetUserContent(v_userContent);
  Cluster.SetUserIterator();

  where v_userContent is a vector of strings of the varibales you are getting info on
   

2) In produce() of Prodcuer, fill the output vectors

   // Tell ClusterSummary which Tracker Partitions you want summary information from
   Cluster.SetUserModules( mod ) 


   //Fill generic vector to hold any variables. You can fill the vector based on the name of the variables or the location of the variable within userContent
   cCluster.SetGenericVariable( "sHits", mod_pair2, 1 );
   cCluster.SetGenericVariable( "sSize", mod_pair2, Summaryinfo.clusterSize() );
   cCluster.SetGenericVariable( "sCharge", mod_pair2, Summaryinfo.charge() );


   // Once the loop over all detIds have finsihed fill the Output vectors
   Cluster.SetUserVariables( mod );


  // Dont forget to clear all the vectors and arrays at end of each event




[If putting reading back ClusterSummary from anlayzer]

   You can access all the summary vectors in the following way

   Handle< ClusterSummary  > class_;
   iEvent.getByLabel( _class, class_);
      
   genericVariables_ = class_ -> GetGenericVariable();   

   //You can access the variables by genericVariables_[i][j] where 'i' is the order in which the variable was stored, see enum VariablePlacement
   cout << genericVariables_[0][1] << endl;
   cout << genericVariables_[1][1]/genericVariables_[0][1] << endl;
   cout << genericVariables_[2][2]/genericVariables_[0][2] << endl;

   --or--
   
   //You can access the variables by the variable and partition name.
   cout << class_ -> GetGenericVariable("cHits", ClusterSummary::TIB) << endl;
   cout << class_ -> GetGenericVariable("cSize", ClusterSummary::TIB)/class_ -> GetGenericVariable("cHits", ClusterSummary::TIB) << endl;
   cout << class_ -> GetGenericVariable("cCharge", ClusterSummary::TOB)/class_ -> GetGenericVariable("cHits", ClusterSummary::TOB) << endl;
