L1Tracks

The L1Tracks branch consists of a TClonesArray of CTT tracks.

Header file: trigsimcert/L1Track.hpp

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

Information taken from l1l2_evt/l1ctt_reco.hpp

Accessor Method used    
Sector() l1trk_sector(int i) int sector number of the CTT track
PtBin() pt_bin(int i) int $p_T$ of the CTT track (0: $p_T$=1.5-3.0 GeV, 1: $p_T$=3.0-5.0 GeV, 2: $p_T$=5.0-10.0 GeV, 3: $p_T>$10 GeV)
LowerPt() from PtBin() float lower edge of the $p_T$ bin for a track found by the L1CTT trigger (value of 1.5, 3.0, 5.0 or 10.0)
UpperPt() from PtBin() float upper edge of the $p_T$ bin for a track found by the L1CTT trigger (value of 3.0, 5.0, 10.0 or 999.0)
Charge() charge(int i) int charge of the CTT track
CPSMatch() l1trk_cps(int i) int CPS track match flag (0: no match, 1: loose match, 2: tight match) for the CTT track
Occup() l1trk_occup(int i) int occupancy (varying between 0 and 240) for the CTT sector in which the track was found
Iso() l1trk_iso(int i) int isolation (0: not isolated, 1: isolated) of the CTT track (isolated if it is the only track in the sector and the 2 adjacent ones)
NCPS() l1trk_numcps(int i) int number of CPS clusters (varying between 0 and 3) for the CTT sector in which the track was found
Phi() from Sector() float azimuthal angle of the track
