- •
Data from multiple stellar occultations are used to study waves in Saturn’s B ring.
- •
Different parts of the Janus 2:1 wave appear to have different pattern speeds.
- •
The B-ring’s typical surface mass density appears to be between 40 and 140 g/cm2.
- •
The B-ring’s surface mass density is not strongly correlated with optical depth.
