[Halld-cal] BCAL trigger commissioning

[Elton Smith]

Hi Andrei,

Please go ahead and post your preliminary results so that we can take a 
look at them. I believe that Zisis is on travel tomorrow and Matt and I 
are participating in the Future Directions workshop, so we might not 
have a meeting tomorrow. It will be very useful to see how your numbers 
compare to the ones that we are currently using.

Thanks, Elton.
