    keyword=putting in Pb/D tgt 1

    midnight -- we put in Pb/D tgt 1 (which has never seen beam)

    Confirmed BDS position matched expectation to within 4 units.

    laser 65, slit 15
    L-HRS rate = 90 kHz
    R-HRS rate = 87 kHz

    adjust slit to 13.5

    L-HRS rate = 1600 Hz
    R-HRS rate = 1100 Hz

    adjust slit to 14

    L-HRS rate = 16 kHz
    R-HRS rate = 15 kHz

    Start a run
    L-HRS 27851. R-HRS run 6920
    Not hitting any frame. See fig 1.
    Present raster is 23 x 9.5 (MCC) = 6 x 4 (spot++)

    Increase the raster to 36.6 x 19 (MCC) = 9.5 x 8 (expected spot)

    Do runs 27852 and 6921

    We are hitting the frame in Y on both sides.
    And it seems like we're hitting in X.

    Next: make raster 30 x 15 and scan around in X,Y.
