    keyword=the position difference caused by current

    I choose 3 position's DAQ value and EPICS value in different
    current(50nA,75nA,100nA), you can see the difference in the attachment. 
    In each picture you can see three parts, each part has same position ,
    just different current, I tagged the epics value in each part. the epics
    value comes from:
    IPM1H05A.XPOS
    IPM1H05A.YPOS
    IPM1H05B.XPOS
    IPM1H05B.YPOS
