    Entry number 185333


    keyword=spot++ seems abnormal

    Salvatori ran spot++, and discovered that the beam spot appears to be somehow different (compare with halog 184735). The bpm strip charts don't show any particular excursion in position. It sure looks like a 1mm or so beam offset in the vertical, but the bpms don't seem to suggest this.

    Could it be a fast excursion which is not seen by the time-averaging bpm EPICs readback?
