where: a = x, y, d, l1, l2, or µ; t = t1 - t0 (decimal hours), and t0 = 8.000 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 5.00 < t1 < 11.00 TDT. Note that all times are expressed in Terrestrial Dynamical Time (TDT).
