The LVL1 jet transverse energy scale as function of truth jet transverse energy

The LVL1 jet transverse energy scale as function of truth jet pseudo-rapidity .

LVL1 jet transverse energy resolution as a function of truth jet transverse energy LVL1 jet trigger efficiency as function of the offline reconstructed jet ET for different LVL1 energy thresholds

Variation in the (a) transverse energy, (b) phi position and (c) eta position of jets as function of number of iterations performed by the LVL2 jet reconstruction algorithm. The area of the boxes is proportional to the number of entries in each bin.

Time spent by the LVL2 jet reconstruction algorithm for two different window sizes: 1.4x 1.4 (dashed line) and 1.0x1.0 (solid line).

Jet energy scale for the LVl2 jets as a function of the truth jet ET (a), for four different bins in eta. Jet energy resolution as a function of the truth energy of the jet (b), for four different bins in eta. These results are obtained after calibration.

The total processing time per event (a) for the LVL2 jet algorithm. The solid line is the processing time measured using the FEB-based method (mean 13 ms). The dashed line is the processing time measured using the cell-based method (mean 22 ms). The total data collection time per RoI (b) for both the cell-based and FEB-based data unpacking methods.

LVL2 jet algorithm processing time per jet RoI for the cell-based method (a) and FEB-based method (b). The total processing time is shown together with the execution time of the individual steps involved in the LVL2 jet reconstruction.

EF trigger efficiency as function of offline jet transverse energy for two different trigger signatures consisting of a set of LVL1, LVL2 and EF trigger thresholds: (a) E_T_LVL1 > 10 GeV , E_T_LVL2> 23 GeV , E_T_EF > 48 GeV ; and (b) E_T_LVL1 > 70 GeV , E_T_LVL2>151 GeV , E_T_EF> 256 GeV .

Execution time per RoI for different steps in the EF data preparation (a) and the jet reconstruction.
