  2. Remaining issues:
    • Tagger hodoscope time shifts
    • communication with accel. w.r.t. tagger magnet - Paul Vasilauskis (Ops group leader): "I am putting out to my staff to contact the hall if they do need to touch the magnet and am looking into adding wording to the magnet screens"
    • BCAL noise at 10 o'clock
    • Bleedthrough
