    keyword=MPS disagreement in Sync Check 1 for Run 1602

    Looks like the TS12 reboot did not solve all our problems. We're now seeing a small number of events where the 792 and 1881 MPS values do not agree (Fig. 1, top pane). Helicity looks good though (bottom pane).

    The syncroc signals look pretty good (Fig. 2), but the discontinuity problems Ellie noticed were intermittent -- not present in every run -- so we can't say yet whether it's "fixed" after the TS12 reboot.
