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 = 18.000 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 15.00 ≤ t0 ≤ 21.00 TDT.
Note that all times are expressed in Terrestrial Dynamical Time (TDT).
Saros Series 121: Member 56 of 71 eclipses in series.
Predictions for the Annular Solar Eclipse of 1935 Dec 25 were generated using the VSOP87/ELP2000-82 solar and lunar ephemerides and a value of ΔT = 23.8 seconds. The accuracy of the northern and southern edges of the eclipse path are limited to approximately 1-2 kilometers due to the lunar limb profile.
