[Halld-pid] Naming the TOF HV channels

[Fernando J. Barbosa]

Hi Paul, Nerses,

Specifically,
TOF-N-1 to 44
TOF-S-1 to 44
TOF-UP-1 to 44
TOF-DW-1 to 44

Obviously, the same paddle has TOF-N-1 and TOF-S-1 and so forth.

Best regards,
Fernando

Hi Paul, Nerses,

Gluex-doc-2018 should be followed. All the cables are already labeled accordingly.

Best regards,
Fernando

Hi Nerses,

I like what you propose, and as I mentioned it is important the follow a general convention. 

My concern that we keep the plane orientation information which is provided in the {N,S,T,B} scheme. To change these later values from letter to number would would require a change of the [1,2] to something like [H(orizontal),V(ertical)]. I say we keep it as you propose, but I will pass this information on to others in the TOF group for their concerns.
