    Shift summary:
    ==============
    Half-wave plate was changed at the beginning of the shift. It is now OUT. Some problems with the right arm at the end of the shift. Other than that, smooth running...

    --------
    00:00 Shift started with production run 4840 underway.

    00:38 Half-wave plate changed: it is now OUT (see HALOG entry 137126).

    01:28 Bleedthrough measurement: 0.0000 uA, 0.00% (ELOG entry 1245777). Hall C was running at 37uA. A bit strange, I'll request another measurement later on.

    04:15 Compton CODA rebooted. A couple of junk runs.

    06:25 Bleedthrough measurement: 1.36% (ELOG entry 1245806). Hall C running at 78uA.

    07:30 Right arm magnets problems (see HALOG entry 137151).

    08:00 Run 4850 underway. Ramping right magnets up.

    Compton run summary
    ===============================
    Run 9606 : Probably junk, or requiring careful analysis. The half-wave plate was changed in the middle of the run.
    Run 9607 : Polarisation 72.8%, S/N=0 (??). Half-wave plate appears IN in the run analysis page. I don't know if that is important.
    Run 9610 : Polarisation 77.2%, S/N=18.4.
    Run 9611 : running...
