Dear all

The method we used to correct the photon energy based on pi0 data is described in the CLAS note 2006-015

https://misportal.jlab.org/ul/Physics/Hall-B/clas/viewFile.cfm/2006-015.pdf?documentId=290

The photon sampling fraction is not exactly the same as the electron unfortunately, and I do not believe we can entirely on the simulations.

Further discussion in CLAS note 2013-004

https://misportal.jlab.org/ul/Physics/Hall-B/clas/viewFile.cfm/2013-004.pdf?documentId=700

At the moment I would suggest to only use pairs of photons in the same sector

Best regards
FX
