    Production, He3 transverse.

    Took runs 4042-4046 and then 4054-4058,
    while 4047-4051 are junk and 4046,4054 had deadtime = 25%.
    4052 is a spot++ check at 5 uA.
    4053 was very brief (had to resurrect start/end-run popups).

    The deadtime increased after run 4045 because when we reset BB
    HV we turned on Cherenkov which had an unexpected but demonstrable
    effect on deadtime. I suppose 4046 and 4054 are "ok".
    I'm wondering if we should set Cherenkov HV to zero to avoid
    this problem in the future (so if its enabled it does nothing) ?

    Other events:

    1. Had to restart adaql10 twice (see halogs 251379 and 251387).
    adaql10 is now on its own private UPS.

    2. Power-cycled TS11 VME crate (20 min. access) to solve SCALER=-1
    problem. Is there a remote power-cycling procedure ?

    3. Discussion about RICH hit rejection (see halog).

    4. Fixed the auto-BANU.
