Multivalue integration of the planetary equations over the last one-million years.
Abstract
Ephemerides spanning the last 1 Myr for the nine planets have been constructed from data generated by a numerical integration of the nonrelativistic planetary equations. Initial data were taken from DE200. The data were used to establish two data bases. One contains the osculating Keplerian elements of the earth at 150-day intervals, and the other holds the averaged Keplerian elements for all nine bodies recorded at unequal intervals of 10 revolutions per body. The integration was performed using a 12th-order multivalue Nordsieck procedure written for efficient implementation on an array processor. The focus of the paper is on the graphical representation of the evolution of the averaged elements.
