tan f2 = 0.0046593

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

a = a0 + a1t + a2t2 + a3t3    (or a = Σ [antn]; n = 0 to 3)

where: a = x, y, d, l1, l2, or ; t = t1 - t0 (decimal hours), and t0 = 10.000 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. Thus the Besselian elements are valid over the period 7.00 ≤ t1 ≤ 13.00 TDT.

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