Spatially resolved BPT classification maps based on [OIII]/Hβ versus [NII]/Hα BPT diagrams for SDSS1510+07, UGC 7342, SDSS1524+08 (top from left to right), NGC 5972, and the Teacup (bottom from left to right). The color bars indicate the different BPT regions, where green indicates the spaxels fall in the Seyfert section of the diagram, red for LINER, blue for composite, and yellow for star forming. Every color is weighted with the [OIII] emission-line flux to more clearly show the bright photoionized regions.
