    keyword=PZT mirror tests

    From approx 10:30 we start PZT mirror tests.
    The test involves modulating a piezoelectric driven
    mirror at the polarized source on a helicity correlated
    basis. The amplitudes are adjusted during runs, and
    recorded as EPICS variables in the Parity data stream.
