# 2008.09.16 QA plots for maximum sided residual (obsolete)

Ilya Selyuzhenkov *September 16, 2008*

** These results are obsolete. Please use this link instead **

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.
