Table 2
Relevant empirical parameters for the four 24 h intervals in Table 1 used in our analysis.
| Encounter | V (km s−1) | δu0 (km s−1) | VA (km s−1) | MA | θc | χc (%) | χ30(%) | ϵc | ϵ30 |
|---|---|---|---|---|---|---|---|---|---|
| E1 | 315 | 40 | 82 | 3.8 | 23° | 56 | 43 | 0.24 | 0.19 |
| E2 | 400 | 37 | 182 | 2.2 | 12° | 63 | 10 | 0.34 | 0.14 |
| E3 | 490 | 49 | 157 | 3.1 | 17° | 52 | 18 | 0.25 | 0.15 |
| E4 | 300 | 38 | 114 | 2.6 | 22° | 92 | 57 | 0.19 | 0.14 |
Notes. We note that V is the average spacecraft speed in the solar wind frame, δu0 is the rms value of velocity at the large-scale (T = 8 min), θc is the critical angle above which the spacecraft can be considered nearly perpendicular to the local field, χc is the fraction of the interval in which the sampling angle is above the critical angle θc, and χ30 is the fraction of the interval in which the sampling angle is above 30°.
