    Re: "Attainment of Precision" article (1964)

    The referenced article was fascinating. I learned far more than I'll ever
    need. I was pleased to note that the author recommended the method for
    determining the error from which the index correction is determined is
    what I tell my students to use: the averaging of horizon measurements by
    bringing them into conjunction from two directions.
