Number of original observations: 1000
Arc : 2004 03 15 — 2006 08 16
Nominal rms: 0².31
Figures show the sample of 15000+1 clones (virtual orbits or VAs—virtual asteroids)
for orbital solution represented by derived nominal orbit.
Orbital clonning procedure was applied
at the epoch of 2006 09 22 — close to observational arc.
The derived swarm of VAs follows the normal distribution in the orbital elements space. This
is visualized by color coding of points in figures below. Each point represents a single virtual orbit, while
the colors indicate the deviation magnitude from the nominal orbit:
red points represent virtual orbits within confidence level of 50%,
magenta: confidence level within 50%—90%,
cyan: remaining points.
In the crowded areas points' symbols heavily overlap.
Projection of the 6-dimensional space of possible
15000+1 osculating orbits of Apophis onto the plane of two chosen
LOV's (line of variations) are given by black dotted lines.
Each individual plot is centered on the nominal values of respective pair of orbital elements denoted by
the subscript '0' (epoch: 2006 09 22).
