    keyword=Change of HV in some of the BB channels

    I have changed the HV for the following channels of the
    dE and E scint. planes:

    Name | CH | old HV | new HV
    ------------------------------------------
    dE - 2L | L7.2 | -1374.0 | -1364.0
    dE - 9L | L7.9 | -1403 | -1388.0
    E - 9L | L11.9 | -1251 | -1241.1
    dE - 6R | L9.6 | -1355 | -1367
    E - 6R | L13.6 | -1285 | -1275.0
    dE - 9R | L9.9 | -1401 | -1396
    E - 9R | L13.9 | -1357 | -1332

    For the purpose of these tests I also changed the prescales for
    the LEFT-DAQ:

    PS1 = 100, PS2 = MAX, PS3 = MAX, PS4 = MAX, PS5 = 1, PS6 = MAX,
    PS8 = MAX

    The dead time is approx. 8%
