The time step and RHSCALE was decreased in the second run (2953-cp1):
d*t* = 2 days, RHSCALE = 1. The number of encounters within
the Hill sphere decreased downto 1 or 10, as we expected.
The most of *a* changes due to encounters is of order
10^{-4}.

The calculation using swift_bs (Burlisch-Stoer) integrator with the same initial conditions. The time span is much shorter than in previous cases (<= slower integrator). Jump in
