Continuum-subtracted Paα flux maps extracted in consecutive velocity steps of 100 km s⁻¹. We measure the standard deviation from the red square box at the bottom right corner of each panel, and we use that to show only emission above 3σ. The velocity interval used to construct the maps is indicated in the top right corner of each panel, in km s⁻¹. The peak of the nuclear Paα emission is indicated with a red cross.
