Left panel: BPT diagram used to distinguish between ionisation by AGN (red spaxels), star formation (blue spaxels), composite (green spaxels), and LINER (yellow spaxels). The figure is adapted from Mezcua & Domínguez Sánchez (2020). Middle panel: The left figure shows the spatial distribution of the BPT-classified spaxels (colour-coded as in the top left panel). Empty squares mark the IFU coverage, grey squares mark those spaxels with S/N > 1. The radio contours at (10, 20, 40, 70) times the off-source RMS noise have been added on the image. The right figure is the SDSS composite image. The pink hexagon shows the IFU coverage. The figure is taken from Mezcua & Domínguez Sánchez (2020). Right panel: VLA radio image at 6 GHz. The colour bar indicates the flux of each pixel in Jy beam⁻¹. Regions selected for Gaussian fitting are indicated by a letter. In the lower right corner is the clean beam (solid white or solid black line), which indicates the minimum beam size resolved in the observation and whose size is shown in Table 2. The radio contours have been added on the image.
