    keyword=BPMA Attenuator Change LHRS

    During the access to fix the AC in the left detector hut, I swapped the
    attenuator being used for BPMA antenna's 1, 2, and 3 to the original one
    before the activities on Friday, November 9, 2007.

    See Halog <a

    I checked the offsets between the new attenuator and the original. The
    offset was set to zero for the new attenuator and about 0.05 V for the
    original.

    Swapping back to the original attenuator should fix the offsets seen in
