---+ # of events in the analysis

   * EMCal trigger (all the centrality) ; 250,000 
   * Central trigger ; 2,000,000

---+ Energy distribution
---++ Energy distribution in EMCal trigger

<img width="900" alt='Pic_eop_fit_expgau_v2.png"' src="%ATTACHURLPATH%/ClusterEcent.png" />

   * %RED%(action)  %ENDCOLOR% Check exotic cluster

---++ Comparison Max tower Energy and All cluster in EMCal trigger

<img width="900" alt='Pic_eop_fit_expgau_v2.png"' src="%ATTACHURLPATH%/ClusterEcentMaxE.png" />
   * Maximum tower energy distribution is identical with cluster energy distribution without any trigger cluster selection above the threshold.
   * In most central, these distributions are different above the threshold

---++ Comparison between EMCal trigger (Central) and Central trigegr

<img width="700" alt='Pic_eop_fit_expgau_v2.png"' src="%ATTACHURLPATH%/ClusterEcomp.png" />
   * Cluster energy distribution with the EMCal trigger in the most central (0-10%) is well match with the distribution with the central trigger 
     after arbitrary scale above the threshold.

   * %RED%(action) %ENDCOLOR%  compare with narrow centrality

---+ E/p 
---++ Central trigger

<img width="800" alt='Pic_eop_fit_expgau_v2.png"' src="%ATTACHURLPATH%/EopCent.png" />

   * Large hadron contamination at low pT due to dE/dx selection. Need to check.

   * %RED%(action) %ENDCOLOR% show the fitting
   * %RED%(action) %ENDCOLOR% first fit the narrow gauss to find peak and width

---+++ E/p peak position & resolution

<img width="600" alt='Pic_eop_fit_expgau_v2.png"' src="%ATTACHURLPATH%/\Pic_Eop_cent.png" />

   * peak position ; ~ 7 % higher than unit

---+ Raw Electron yields
---++ Central trigger (uncorrected background)

   * Uncorrected background hadron correction
<img width="700" alt='Pic_eop_fit_expgau_v2.png"' src="%ATTACHURLPATH%/RawEleCentTrig.png" />
   * %RED%(action) %ENDCOLOR% subtracting background
   * %RED% (action) %ENDCOLOR% compare with cluster energy distribution

---+ %RED% Next to do %ENDCOLOR% 
   * shower shape
   * track matching
   * Occupancy
   * phi and eta dependence of PID (E/p, dE/dx)
   * Increase statistics to see electrons in EMCal trigger
