At time t1 (decimal hours), each Besselian element is evaluated by:
a = a0 + a1*t + a2*t2 + a3*t3
where: a = x, y, d, l1, l2, or μ; t = t1 - t0 (decimal hours), and t0 = 1.000 TDT.

The solar eclipse predictions were made using the VSOP87/ELP2000-82 solar and lunar ephemerides. The resulting Besselian elements from these ephemerides were originally generated for the NASA technical publication Five Millennium Canon of Solar Eclipses: -1999 to +3000.
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. For eclipses five centuries or more centuries in the past or future, the largest uncertainty in the predictions is caused by fluctuations in Earth's rotation due primarily to the tidal friction of the Moon. The resultant drift in apparent clock time is expressed as ΔT and is is based on the work of Morrison and Stephenson [2004].
The Gregorian calendar is used for all dates from 1582 Oct 15 onwards. Before that date, the Julian calendar is used (see Calendar Dates).
