keyword=ep measurement - update
Talked with Jacques Berthod about last ep measurement. He points out that
the position senesitivity at 4.8 GeV is tremendous ~ 15 MeV /mm
Therefore one cannot trust ep with no fast feedback. Hence the systematic errors on
the 4.8 GeV ep are at least 3 MeV as I observed +- 0.1 to 0.2 mm drifts in
beam position.
