Photon isolation for Fragmentation photon. fragmentation photon with parton level isolation e_h>0.5 can also contribute to our final measurement (tight/isolated photons). Sherpa Wgamma 0/1 jet MC. Up to 15% variation. <5% variation. Njet distributions (1fb-1).

Njet distributions (1fb-1) Normalized to cross section with e_h<0.5 Normalized to cross section with e_h<5
Summary • There are significant contribution from fragmentation photon with parton level isolation e_h>0.5 • number of expected signal for Wgamma increased by 15% by loosing parton level photon isolation cut.
