Find, now since you claim that the Orbital Elements are changed
as a result of OBSERVATIONS, please tell us what observation
caused the eccentricity of the mythical Hale-Bopp to change from
0.995038361 on May 28, '96 to
0.995072729 on June 27, '96,
as announced by JPL. Lest you say this was due to perturbations upon the recent passage of Jupiter, where as we have been stating the posted observations of Hale-Bopp had it leaping AWAY from Jupiter upon passage of that giant, other than the fact that this adjustment moved the mythical Hale-Bopp closer to an occultation with Gamma Andromedae, there would be no effect on the ellipse of a passing comet that would TIGHTEN THE LOOP AND THUS NARROW THE ELLIPSE.
This would send such a comet out of the Solar System in an
entirely different place than announced, and thus radically
affect any reentry point, according to your vaunted comet
ephemerides. It would also radically affect any period for an
comet, as a more narrow ellipse would have a shortened length!
Yet everyone kept parroting the same pronounced 4,200 year
period, as though a tape were being played, which was more than
likely the case. We, the Zetas, noting the real reason for this
change, had our emissary, Nancy, record this at the time, as NO
one else was noticing! Such is the case when the Sheep are
allowing themselves to be led by their Shepherds, with blind
trust. The facts are all there, it's just that no one has been
bothering to LOOK at them.
