sPHENIX discussion of software

["Perepelitsa, Dennis" <dvp AT bnl.gov>]

Hi Jin,

Thanks for following up on this late point. Yes, as discussed in the meeting, 
I think it’s a good idea to have a “control” sample without the plug doors so 
we can evaluate the effects. I would suggest an alternate version of the pp 
MB events with steel IHCal to do this.

To sum up, this would bring us to 500k simulated events total, with the 
following event types / configurations: 

        100k p+p MB, steel IHCal, plug doors
        100k p+p MB, steel IHCal, NO plug doors
        100k p+p MB, Al IHCal frame, plug doors
        100k p+Au MB, steel IHCal, plug doors
        100k p+Au MB, Al IHCal, plug doors

Is that right? 

Dennis
