Table 1

Results of field-aligned bubble scale-length estimate based on simultaneous observations of plasma depletions on the same fluxtubes by either one or both Swarm spacecraft. The rows in the upper halve list the numbers of either single-satellite EPB detections by Swarm A or B and the double detections at the various fluxtubes from the considered 28 events. In the lower part the values of parameters for calculating the scale length, L, are listed (see Eq. (4) for the definition).
