Notes.
Based on the original semimajor axis in the Nakano Notes (orbital computations by Syuichi Nakano), http://www.oaa.gr.jp/~oaacs/nk.htm (the original semimajor axis is determined after the integration backward one orbit, under the influence of the Sun and planets, galactic tides, and possibly nongravitational forces and nearby stars).
