23 nurical thod

we utilize a send-order wisdo–hon syplectic ap as our a tegration thod (wisdo ≈ap;ap;ap; hon 1991; koa， yoshida ≈ap;ap;ap; nakai 1991) with a special start-up procedure to reduce the truncation error of angle variables，‘war start’(saha ≈ap;ap;ap; treae 1992， 1994)

the stepsize for the nurical tegrations is 8 d throughout all tegrations of the ne ps (n±1，2，3)， which is about 1/11 of the orbital period of the nerost p (rcury) as for the deteration of stepsize， w
