HST - 1st orbit


A composite of the six exposures.
Separation is 0.87"

Preliminary reduction - July 17

p = 33.35 deg
s = 0.87"
JD = 2452103.38

Ian, Joel and myself have started playing with the images. If you want to do
something with them, let me know...

There are still some checks to be made for the astrometric reduction.
The "final" reduction should not be far from the above values though.



A tentative orbit - July 17 posting

The HST position is close to what we got from Jan. 2000 CFHT observations
Hence the period is close to 550 days or an integer fraction of 550 days.

Well, the best orbit using the ground based observations good enough to be useful
is a short period one... 1/3 the 550 days. Feel free to make your own computation
and le me know what you find. I'll update this page as other results are coming!
