Important Notes About Movies
Please note: That movie 1, although interesting,
IS NOT the newly discovered double. It is showing
the performance of our technique on a known asteroid,
that looks like it is close to being a double, but
actually is connected.
Movie 1. This is a movie of the rotation
of asteroid 216 Kleopatra in Nov 1999, when radar data were
also beign acquired, that showed the weird 'dog-bone'
shape of this asteroid. These data are from CFHT.
The asteroid rotates once every about 5 hours.
Movie 2. Newly discovered main-belt double asteroid
90 Antiope as it rotates completely every 16.5 hours.
