                 Tan f1 = 0.0047348    Tan f2 = 0.0047112

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

            a = a0 + a1*t + a2*t2 + a3*t3    (or a = Σ [an*tn]; n = 0 to 3)

    where:  a = x, y, d, l1, l2, or μ
            t = t1 - t0  (decimal hours) and t0 = 23.000 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 t,0. Thus the elements are valid over the period 
20.00 ≤ t0 ≤ 02.00 TDT (Nov 23 to Nov 24).

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