UVIS Tracking Occultations
No coverage :(
3 tracking
occs
Apart from 3 tracking occultations (A ring and A ring ramp), and
excluding dim stars, other occultations are limited to 10m true
resolution!

Future possibilities
Apart form A ring and A ring ramp we have limited
high resolution coverage of the rest of the rings.
Any occultation with with dl<10m is a gain!
Proposed targets for dl<10m occultations and
examination of ring microstructure:
1. C ring
2. inner B ring (as it is not as opaque)
3. Cassini division
There are only about dozen possibilities in total!
