Flux maps of the Paα emission with contours at 3, 15, 30, 60 σ of the radio VLA 6 GHz high resolution (∼0.25 arcsec beam) image superimposed (black contours). Top panel: systemic Paα emission between −100 and 100 km s⁻¹. Bottom panel: flux map of the Paα emission between −700 and −300 km s⁻¹with the fitted ellipses, at different distances from the central peak, in white and the ellipse used to measure the outflow extent in red.
