    T - universal time ( TDT - UT1 = 66.0 s );
    s - the angular distance between the centers of the Moon and the shadow;
    d - the linear distance between the Moon's center and that of the shadow
        in terms of the shadow's radius;
    P - the position angle of the Moon's disk semi-diameter directed towards
        the shadow's center.
