GTC MEGARA VPH481-MR [O III] λ5007 (top) and VPH665-HR [N II] λ6584 (bottom) channel maps of A 58. Each map shows the integrated emission in the channles within the LSR velocity range labeled on the upper right corner of each map. Contours corresponding to 2.4%, 5%, 11%, 23%, and 48% of the emission peak (1.71 × 10⁻¹⁴ and 1.61 × 10⁻¹⁵ for [O III] and [N II], respectively) are overlaid in all maps (solid white lines). The approximate location of the central star is marked by a white star.
