    keyword=Controlled access to shift BB retimed L1A by -25ns

    The timing on the Cerenkov ADC gate was quite marginal. Xin also noted a ~25--30ns shift in the T0 timing of the MWDC spectra.

    The timing shift was accomplished by pulling one 25ns 'jump' out of the delay on the T6 copy going into the retiming circuit. This should bring the timing closer to where the T1-based retiming used to be (based on the MWDC shift).
