    keyword=BB dE and E-plane Thresholds (?)

    This morning I noticed that the dE and E-plane thresholds appeared to be
    set to -8 mV giving a rate of 80 Hz and 1500 Hz for the dE and E plane 
    triggers.  I guess this has been this way since the last time the camac
    crate was port scanned over the weekend.  The wire chamber thresholds were
    still set correctly.
    
    I changed the thresholds to -50 mV for both E and dE.  The E-plane rate
    doubled to about 160 Hz and the dE rate went up to 6 kHz.  I tried to set
    the dE rate to -100 mV, but it instead claimed to have set it to -36 mV.
    However the rate for dE dropped down to 1.8 kHz instead.
    
    I am confused on what the threshold software is doing.  Perhaps there is a 
    bug in the code.  It also sometimes takes several minutes for the code to
    complete getting or setting the thresholds.
