Brα image reconstructions of IRAS 17163 using WISARD. (Top) Integrated intensity around the Brα emission obtained by summing all velocity channels. (Grid) Velocity-channel reconstructed maps across the Brα line profile (constant velocity step of Δv km s⁻¹), progressing from blue-shifted (top left) to red-shifted (bottom right) emission. In both panels, the reconstructed L-band continuum emission is overplotted as red contours to highlight the spatial extent of the ionised emission relative to the continuum.
