Re: energy thresholds run 8

[petrovge@pnpi.spb.ru]

 Dear Peter!
About EH and EVH i can'nt say something because these values we may define
only after treatment of data of FADC. This question is to Oleg Maev.
Concerning the EL, we set it above of noises and it has fixed value during
of all runs. Electronic's noises, included TPC are approximately 2000
electons RMS. Usually the threshould EL is 6 RMS. We have 1 Hz in this
case noise count. Really pick-up add noises, but i don't know how much is
it. We may to get this information from data of FADC. We wrote to FADC
pulser generater and we can to define RMS from these data.
We may to get RMS's data after treatment data of the pedestal also.
Thank you for question and best regardes. Genna.
