Osculating values of the secular angles – longitude of node Ω (abscissa) and longitude of perihelion ϖ (ordinate) – for members in the Rampo family (epoch MJD 60 000.0). The black symbols show multiopposition orbits, gray symbols are for the singleopposition orbits; diamond symbol for (10321) Rampo, the largest member. Larger/smaller relative values of the secular angles, measured with respect to (10321) Rampo, correlated with positive/negative shift in proper semimajor axis. The node/perihelion trends are opposite, because the node drift in a retrograde sense, while the perihelion drifts in the prograde sense. The dashed line with a slope −0.5 indicates the correlation trend.
