At time t1 (decimal hours), each Besselian element is evaluated by:
a = a0 + a1*t + a2*t^2 + a3*t^3 (or a = Σ [an*t^n]; n = 0 to 3)
where: a = x, y, d, l1, l2, or μ
t = t1 - t0 (decimal hours) and t0 = 7.000 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.
The Besselian elements are valid over the period 4.00 ≤ t0 ≤ 10.00 TDT.
Note that all times are expressed in Terrestrial Dynamical Time (TDT).
Saros Series 125: Member 54 of 73 eclipses in series.
Predictions for the Partial Solar Eclipse of 2015 Sep 13 were generated using the JPL DE405 solar and lunar ephemerides and a value of ΔT = 67.8 seconds.
