    keyword=alignment in Y ok

    Doug H. pointed out that the apparent shadow of the detector was
    constrained in Y by the Y distribution of the radiative tail, and
    does not show how far the detector actually goes. David L. says
    the detector is ~20 cm in Y at this projected location (VDCs) and
    centered on zero to at least +/- 1 cm, so it easily encompasses
    the 5 cm long (in Y) elastic peak. So the detector is certainly
    big enough, and well aligned in Y, and that's the end of this crisis.

    We may want to bump the peak over towards smaller momentum to
    avoid the 20 MeV breakup more. To be discussed.

    Tonight we will cross-align the profile scanner, as planned, but we
    will not do a Q3 quad scan.
