[G12] Plot of the BEC_Factor for the Beam 4-vectors

[Eugene Pasyuk]

Mukesh,

Your version of bosdump truncates names of epics variables.
The name of those you need are: "halla_MeV" and "hallc_MeV"
These are so called "Tiefenbach energies".

You can also look at:
"MBSY1C_energy" - Hall A
"MBSY2C_energy" - Hall B
"MBSY3C_energy" - Hall C
Those are kind of nominal energies at BSY.
