Using StMuDstMaker in a Macro

• void MacroExample( Int_t nFiles, Char_t InputFileList[256] )

• {

• // Load Libraries

• gROOT -> Macro("loadMuDst.C")

• // Create Histograms

• TCanvas* nCanvas[2] ;

• TH1F* histogram[2] ;

• …

• // Run the muDstMaker

• StMuDstMaker* maker = new StMuDstMaker(0,0,"",InputFileList,"MuDst",nFiles) ;

• while ( !maker->Make() )

• {

• // Do 'event' analysis based on event pointers

• StMuEvent* muEvent = maker -> muDst()-> event() ;

• histogram[0] -> Fill( muEvent -> primaryVertexPosition().z() ) ;

• // Get 'track' data, make cuts on tracks, do physics analysis

• TObjArray* tracks = maker -> muDst()-> primaryTracks() ;

• TObjArrayIter GetTracks(tracks) ;

• StMuTrack* track ;

• while ( ( track = (StMuTrack*)GetTracks.Next() ) ) // Main loop for Iterating

• {

• histogram[1] -> Fill( track->pt() ) ;

• }

• }

• // Finish using the muDSTmaker

• …

• histogram[0] -> Draw() ;
