[g13] meeting on Monday

[Pawel Nadel-Turonski]

Hi Ken,

I am not sure I agree with your conclusion that the number of particles 
per event can be a trigger issue considering the fact that the trigger 
did not change. The only thing different was the extension of the ST 
window, to make sure that no events were missed. Thus, the trigger 
before 53333 (which was identical to that in g11) is a subset of that 
after 53333. In order for the average multiplicity to increase, it would 
have to be extremely high for the events when there are only two single 
hits in the ST separated by a time larger than the g11 setting allowed, 
which are the ones that were added post 53333.

Cheers,

    Pawel
