Slide 3:
Should not cut on vertex ranking in AuAu.

Slide 5-7:
Test of the matching efficiency can be done with photonic electrons (by doing photonic electron selection before the matching procedure)
The results of the test should then be used to introduce the cuts on plots from slide 6 and 7.

Slide 8:
erratum: the second cut is performed on p, not p_T, as written on the slide.
There is a need to introduce SMD cut, SMD clusters should be used for that instead of EMC points

Slide 9:
The excess in Like-Sign background, visable especialy in the 3D InvMass after cut shows up most likely due to hadron contamination.
A cleaner sample of sister tracks sould be used by introducing a cut p_T>0.2 GeV/c. A harder cut on dE/dx can be also considered.

Slide 10:
To get the information which BEMC tower fired the trigger a TriggerSimulator should be used. For the details I should contact Pibero Djawotho or Renee Fatemi, who are the autors of that piece of software.

General remarks:
A purity study of electron sample is highly recomended to avoid hadron-D⁰ correlation.
