Results of pixel-by-pixel emission-line fitting. In the left panel we show the flux distribution of the [O II] doublet in units of 10⁻¹⁸ erg s⁻¹ arcsec⁻²; the two crosses mark the location of the peak of emission in the red and blue components; i.e., of the two active nuclei. In the central panel we present the gas velocity, and in the right panel we show its velocity dispersion, both in km s⁻¹ units.
