    keyword=New vernier positions measured 1/12/01

    Moved the lifters to 3814520. This is the same position on the resolver as the 1/10/01 measurement. The new postions are:

    Note: all dimensions are lengths in units of Inches

    Downstream lifter (slave 2) 26.640
    Beam right lifter (slave 1) 26.612
    Beam left lifter (master) 26.530

    The offsets today compared with 01/10/01 are shown below

    Lifter offset on 1/10 ofset on 1/12
    Master 0 0
    Slave 1 -0.082 -0.090
    Slave 2 -0.110 -0.102

    The difference between the master positions of today and 1/10 is 0.016 inches.
    This is more or less a typical repeatability error.
