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

[Mukesh Saini]

Hi Eugene,

I was able to find the following variables that vaguely resemble beam energies from the different halls in the sector 0 of the EPICS bank

==========EPIC : Sector: 0=================
value: 1193.317  name: MBSY1C_e
value: 5724.001  name: MBSY2C_e
value: 5728.524  name: MBSY3C_e

value: 1192.183  name: halla_Me

value: 5710.992  name: hallc_Me

value: 565.000  name: MMSENTRY
value: 1193.562  name: MMSHLAE 

value: 5713.562  name: MMSHLBE 

value: 5713.562  name: MMSHLCE 

value: 555.000  name: MMSLIN1E
value: 575.000  name: MMSLIN2E

value: 1192.183  name: HALLA:p 
value: -0.000  name: HALLC:dp
value: 5710.992  name: HALLC:p 
=============================

Let me know which are the relevant ones we should be looking at. I am also attaching the EPIC dump from one of g12 runs in case the relevant variable is not in here.

Thanks,
Mukesh.
