Resolved BPT diagram for ALESS073.1 host galaxy (narrow) and outflow (broad) component. Upper panels: spatially resolved map of the observed values of log([N II]/Hα) for the narrow and broad components from left to right, respectively. Lower panels: the spatially resolved BPT where every spaxel in the galaxy is color-coded according to its value of log([N II]/Hα) for the narrow and broad components, from left to right, respectively, as in the histogram in the upper right panel.
