                             Tan ƒ1 = 0.0046340    Tan ƒ2 = 0.0046109

            At time t1 (decimal hours), each Besselian element is evaluated by:

               a = a0 + a1*t + a2*t^2 + a3*t^3    (or a = Σ [an*t^n]; n = 0 to 3)

                  where:    a = x, y, d, l1, l2, or μ
                            t = t1 - t0  (decimal hours) and t0 =  9.000 TDT


            The Besselian elements were derived from a least-squares fit to elements
            calculated at five uniformly spaced times over a six hour period centered at t0.
            The Besselian elements are valid over the period  6.00 ≤ t0 ≤ 12.00 TDT.

            Note that all times are expressed in Terrestrial Dynamical Time (TDT).
