sPHENIX EMCal discussion

[Edward Kistenev <kistenev AT bnl.gov>]

Jin, Sunday is HCAL standalone day. We are planning to take ~500k events at 
each of 4 or 5 energies (30/16/8/4 and maybe 2 GeV/c) - enough data to have 
~2k events for every hodoscope crossing. If you have comments, suggestions - 
welcomed. Would be great to get some insight from this data fast.
The first run (30GeV/c mostly negative pions) is 3285.

                        Edward

Hi, Martin and all

Thanks! This flag is very convenient. This switch is incorporated into a 
not-yet-merged prototype3 production code: 
https://github.com/blackcathj/coresoftware/commit/3236ced2bc2c604a94ab94cd8f3fa9a1daa9259a
 

Now I will also appreciate if someone could point to me the new HBD channel 
map for high-eta EMCal, which will put here:
https://github.com/blackcathj/coresoftware/commit/3236ced2bc2c604a94ab94cd8f3fa9a1daa9259a#diff-4943c7156628a48058c793384d2269b3
 

Cheers,
