tan f1 = 0.0047348

tan f2 = 0.0047112

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

where: a = x, y, d, l1, l2, or ; 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 t0. Thus the elements are valid over the period Nov. 23 20.00 < t1 < Nov. 24 02.00 TDT. Note that all times are expressed in Terrestrial Dynamical Time (TDT).
