\smallskip
The first column in Table~1 indicates the spacecraft (Helios~1 or~Helios 2), $T_{\rm c}$ in the second column is the time for the
observation of the MC center (or for the minimum approach distance).
The MCs are separated in two groups: perturbed (P) and non-perturbed
(N) by a fast SW stream. $\Delta V_x/(t_{\rm out}-t_{\rm in})$ is minus the
fitted slope of the temporal velocity profile (see, Eq.~(\ref{dV}))
and~$\zeta$ is the non-dimensional expansion coefficient
(Eq.~(\ref{zeta})). $\Delta V_x/(t_{\rm out}-t_{\rm in})<0$ means observed
compression of the MC. The average values and the standard
deviations are given at the bottom.
