Data sets:
- pp2006 - STAR 2006 pp longitudinal data (~ 3.164 pb^1) after applying gamma-jet isolation cuts.
- gamma-jet - data-driven Pythia gamma-jet sample (~170K events). Partonic pt range 5-35 GeV.
- QCD jets - data-driven Pythia QCD jets sample (~4M events). Partonic pt range 3-65 GeV.
Notations used in the plots:
- Fit peak energy:
F_peak - integral within +-2 strips from maximum strip
Maximum strip determined by fitting procedure.
Float value converted ("cutted") to integer value.
- Data peak energy:
D_peak - energy sum within +-2 strips from maximum strip (the same strip Id as for F_peak).
- Data tails:
D_tail^left and D_tail^right.
Energy sum from 3rd strip up to 30 strips on the
left and right sides from maximum strip (excludes strips which contributes to D_peak)
- Fit tails:
F_tail^left and F_tail^right.
Same definition as for D_tail, but integrals are calculated from a fit function.
- Maximum sided residual:
max(D_tail-F_tail)
Maximum of the data minus fit energy on the left and right sides from the peak.
