Emission maps of the two auroral lines [N II] λ 5755 (upper panels) and [O II] λ 7330+ (lower panels), without and with correction from recombination (left and right panels, respectively). The correction is obtained using Eqs. (2) and (1), adopting Te = 6000 K and ne = 10 000 cm3. The flux is expressed in units of erg cm2s_1 Å−1 and in logarithmic scale.
