    Start horizontal beam position scan (rastered) with Pb(Lp3) tgt:

    A, B stands for BPMs, 5uA All Runs
    Runs 22118/4245 (xA,xB)=(0.3,0.0) (yA,yB)=(-0.1,0.0)
    Runs 22119/4246 (-0.2,-0.5) (-0.2,0.0)
    Runs 22120/4247 (-0.8,-1.0) (-0.2,0.0)
    Runs 22121/4248 (-1.5,-1.5) (-0.2,0.0)
    Runs 22122/4249 (-1.9,-2.0) (-0.2.0.0)
    Runs 22123/4250 (-2.4,-2.5) (-0.3,0.0)

    Runs 22128/4255 (-4.5,-5.0) (-0.5,0.0)

    Looking at results of scans: must set beam at -3.5 on BPM A and B.
