    keyword=Emiss and right magnet field drifting, frozen ioc

    During the last night the right magnet IOC ran badly and eventually frozen.

    The effects on missing energy is visible in the attached plots: corrected emiss on first plot (run by run),
    position of the carbon peak on the second plot vs run number (square = peak max, triangle = gauss fit center)

    The problems started around run 1665 and had fixed after IOC reboot at run 1681.

    Since the shift is quite constant in time, it can be possible be corrected.
