L1CalEMTwrs/L1CalTwrs

L1CalTwrs and L1CalEMTwrs are two distinct branches in the output ROOT tree. They are TClonesArray's of the same L1CalTwr class (which contains information about a single tower) so they contain the same variables which are filled by very similar methods. They return calorimeter information on a tower-by-tower basis and the towers are sorted by transverse energy in descending order. Eta() and Phi() have been remapped (see l1l2_evt/src/l1cal_reco.cpp for explanations)

Header file: trigsimcert/L1CalTwr.hpp

Package containing the class used to fill the chunk read: l1l2_evt

Information taken from l1l2_evt/l1cal_reco.hpp

Accessor Method used    
Et() emTT(iEta(),iPhi()) float total energy in a calorimeter (EM) tower
  totTT(iEta(),iPhi())    
Eta() etaEM(iEta()) float pseudorapidity of a calorimeter (EM) tower (after remapping)
  etaTOT(iEta())    
Phi() em_phi(int i) float azimuthal angle of a calorimeter (EM) tower
  tot_phi(int i)    
iEta() em_ieta(int i) int pseudorapidity bin number of a calorimeter (EM) tower
  tot_ieta(int i)    
iPhi() em_iphi(int i) int azimuthal angle bin number of a calorimeter (EM) tower
  tot_iphi(int i)
