Properties of phase speeds from the wavelet analysis.
| Parameter | Mean | Median | Std. dev. | Right. | Left. |
|---|---|---|---|---|---|
| Brightness temperature | −29 | −44 | 250 | 28% | 72% |
| Absolute values | 148 | 74 | 204 | ||
| Horizontal displacement | −12 | −27 | 222 | 32% | 68% |
| Absolute values | 103 | 52 | 197 | ||
| Width | −3 | −6 | 268 | 46% | 54% |
| Absolute values | 86 | 28 | 254 | ||
Notes. Mean, median, and standard deviation of phase speeds and their absolute values (in km/s) for oscillations in brightness temperature, horizontal displacement, and width along the selected fibril shown in Fig. 1. The last two columns show the percentage of rightward-propagating (positive velocities) and leftward-propagating (negative velocities) waves.
