Completed Data driven estimation with background subtraction. (Evgeny)

Double check fragmentation photon uncertainty. (Zhijun)

Cross check acceptance and correction factor for electron channel (Tian)

Signal acceptance and efficiency for different SM and ATGC samples in electron channel( Tian, Zhijun)

ATGC part (Minghui, H,Liang)

Double check the numbers are consistent with cross section measurement part.

Include additional systematic due to ATGC dependence on acceptance and correction factors

MC coverage test.

MET acceptance uncertainty

Follow WW analysis : https://cdsweb.cern.ch/record/1395559/files/ATL-COM-PHYS-2011-1522.pdf

Cell out term: quote 13.2% uncertainty on this term.

In-time pileup : quote 3% uncertainty

Out-of-time : 33% of signal MC need to be smeared

Mutag term
