Conductance maps of the northern auroral region during PJ1. (a) and (b) represent the kappa Pedersen and Hall conductance maps, respectively. The ratios of the conductance map computed with a kappa electron energy distribution over the conductance map computed with a mono-energetic electron energy distribution are also represented for the (c) Pedersen and (d) Hall conductances. For the ratio maps, the scale goes up to 2 but the ratio can be locally higher. On each map, the red or green star represents the subsolar longitude.
