    00:25 Start the test:

    *Here are the initial values:
    IGLdac3:ao_0 = 5.0 ..... (PZT X)
    IGLdac3:ao_1 = 5.0 ..... (PZT Y)
    IGLdac3:ao_3 = 1.0 ..... (IA)

    I =50 uA, Beam Energy = 4712.9
    Charge FB=OFF, Position FB=OFF
    5,000 pairs each run.
    Error on charge asymmetry~16 ppm

    Parity DAQ
    Run# ........ X......Y......IA.......BCM1.....BCM2
    ...................V.......V......V...........ppm......ppm
    1171 .........5.0......5.0....1........ 0723.......0733 @00:59 June 15

    1180 .........5.0......5.0....0........ 0342.......0349
    1181 .........5.0......5.0....1........ 0725.......0749
    Finish IA. Set IGLdac3:ao_3 = 1
    -> IA slope ~ 350 ppm/V

    Now test PZT:
    Error on charge asymmetry~16 ppm
    Error on position differences ~ 200 nm

    1195 .........5.0......5.0....1........ 0717.......0764.......514... -1436...482...-331

    Finish PZT. Set IGLdac3:ao_0 = GLdac3:ao_1 =5 V
    The setup values as before.
