At time 't_1' (decimal hours), each besselian element is evaluated by:
where: t = t1 - t0 (decimal hours) and t0 = 17.000 TDT
The Besselian elements were derived from a least-squares fit to elements
calculated at five separate times over a six hour period centered at t0.
Thus the Besselian elements are valid over the period 14.00 .LE. t0 .LE.
20.00 TDT.
Saros Series 130: Member 51 of 73 eclipses in series.
