Beginning-of-run EPICS data for Run Number 1820 at Mon Jan 28 21:10:22 EST 2002
; (Integer!) prescale factors for runs.
; This file is read at start of every run.
; Do NOT put spaces in string, NOR add 2nd string. (REALLY!!!)
; The default factor is essentially infinite.
; ps8 = 65535 turns off the 1 kHz pulser on T8.
; Keep enough T2 and T4 to measure efficiency
; PS1 for the calorimeter singles based on summers
; PS2 for the cosmic trigger for calorimeter
; PS3 for the Left spectrometer based on T3 - S1+S2
; PS4 for the Left spectrometer redundant trigger S1+S2 or
; based on S1+S0 or S2+S0
; PS5 for Coinc. trigger based on S0 and Calo
; PS6 for laser
; PS7 for the Left spectrometer based on S0, timed with calorimeter
; PS8 for pulser
