[Eg6_analysis] IC calibration

[Stepan Stepanyan]

Hello Mohammad,

My first thoughts will be it does not matter what corrections you will use.
Just keep in mind that getting a narrower pi0 peak is not the ultimate 
goal.
The goal is to get energy and angles of photons measured correctly, since
that is what will end up in your calculations of kinematics for DVCS.

Regards, Stepan
