Table 2.
Q − U loop speeds and fraction of scans that are clockwise.
| Time Interval | ΩQU deg tg−1 | Clockwise Fraction |
|---|---|---|
| April 21 | −2.7 ± 0.7 | 0.60 ± 0.08 |
| April 22 | −0.8 ± 0.4 | 0.55 ± 0.03 |
| April 24 | −1.9 ± 0.4 | 0.72 ± 0.05 |
| April 25 | −0.9 ± 0.5 | 0.61 ± 0.09 |
| All Days | −1.6 ± 0.9 | 0.62 ± 0.09 |
Notes. Negative pattern speeds correspond to clockwise motion, for which there is a clear bias.
