Re: BCAL time resolution update

Hi Alex,

I assume all the cuts you made are the same. Does anyone have any idea 
what would have changed or is different in the data file to give you a 
better 1/sqrt(E) fit? I had to make some ssignificant cuts on the ADC to 
get a fit like that otherwise it follows 1/E.
