    A strong peak appeared in the coin spectrum in Run 4658..
    It is not present in any other run. We will replay it.
    The peak was still there.

    Plan is to make a controlled access at 1630
    to move BB to 48 deg and have JP fix the target cooling fan
    Production running will continue at kinematics F after the change
