Artist's drawing

Sketch of the idealized profile of the magnitude of the magnetic field around the vicinity of the plasma sheet of the HCS, and its defining parameters, all with respect to the timing of the current sheet crossing time, indicated by the abrupt rotation of the field in the current sheet by the angle omega. The field parameters are: the left- and right-side lobe-field instensities, and the "plateau" and minimum (dip) field values.
