Table: Past Orbits

Past distributions of the aphelion distance (Q) and the perihelion distance (q) for comets with 0 < 1/a_ori,NG < 10^-4 AU^-1

Non-gravitational (NG) and gravitational (GR) results, GR are presented for comparison

These distributions are described in columns 8-9 either by: A) a mean value for the normal distributions, or B) – three deciles at 10%, 50%, and 90%. The mean values or percentiles of Q and q are given for the swarm of comets at previous perihelion (if all clones are returning), or for synchronous swarm of clones at ~120000 AU from the Sun (if all of clones are escaping). For the mixed swarm of clones the returning part of swarm and escaping part of swarm are additionally treated separately.

In the 10^th column the values of 1/a_ori for the original swarm of clones at ~250 AU from the Sun are given;

11^th column gives percentage of VCs that one can call dynamically new, basing on previous q statistics.

For mixed swarm of clones:

[s] denotes the synchronous swarm of clones,

[R] – values calculated for the returning part of swarm,

[E] – values calculated for escaping part of swarm,

[n] – nominal clone is inside the given part of swarm
