tan *f*_{1} = 0.0046826
tan *f2 = 0.0046593*

At time *t*_{1} (decimal hours), each Besselian element is evaluated by:

*a = a*_{0} + a_{1}t + a_{2}t^{2}
+ a_{3}t^{3}
(or *a = Σ [a*_{n}t^{n}]; *n* = 0 to 3)
where: * a = x, y, d, l*_{1}, l_{2}, or *µ*;
*t = t*_{1} - t_{0} (decimal hours), and
*t*_{0} = 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
*t*_{0}. Thus the Besselian elements are valid over the
period 7.00 ≤ *t*_{1} ≤ 13.00 TDT.

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

Saros Series 139: Member 29 of 71 eclipses in series.
