Total plasma density at the center of the current sheet \({\rho }_{0}\), at Callisto \({\rho }_{{at\; Callisto}}\), electron density at the center of the current sheet \({n}_{0}^{{electrons}}\), and electron density at Callisto \({n}_{{at\; Callisto}}^{{electrons}}\). The estimated equatorial longitudes of the MAW and TEB spots, for each plasma sheet scale height \(H\) and for an electron characteristic energy \(E=10\) keV are indicated in the last two rows. The best fit correponds to H = 0.94 R_J column.
