ECLAT Cluster Spacecraft Magnetotail Plasma Region Identifications (2001–2009)

Table 3

3σ values of plasma flow velocities determined from all flow velocities recorded in plasma sheet regions during one tail season (July–October). Values are used as thresholds in determination of the percentage of high speed flow during region intervals.
