Properties of the MaNGA galaxy M-8454-12701. Panel a: surface brightness distribution across the image of the galaxy in sky coordinates (pixels). The value of the surface brightness is color-coded. The circle shows the photometric center of the galaxy, the solid line indicates the position of the major photometric axis of the galaxy. Panel b: observed (line-of-sight) Hα velocity field in sky coordinates. The plus sign denotes the kinematic center of the galaxy determined from the Hα velocity field. The dashed line indicates the position of the major kinematic (Hα) axis of the galaxy. Panel c: observed stellar velocity field. The triangle denotes the kinematic center of the galaxy determined from the stellar velocity field, and the dotted line indicates the position of the kinematic major (stellar) axis of the galaxy. Panel d: BPT diagram. The symbols are individual spaxels. Solid and long-dashed curves mark the demarcation line between AGNs and H II regions defined by Kauffmann et al. (2003) and Kewley et al. (2001), respectively. The short-dashed line is the dividing line between Seyfert galaxies and LINERs defined by Cid Fernandes et al. (2010). The black points are AGN-like objects according to the dividing line of Kewley et al. (2001). The blue points are the H II-region-like objects according to the dividing line of Kauffmann et al. (2003). The red points are intermediate objects located between the dividing lines of Kauffmann et al. (2003) and Kewley et al. (2001). Panel e: locations of the spaxels with the AGN-like, H II-region-like, and intermediate spectra on the image of the galaxy. Panel f: abundance distribution across the image of the galaxy in sky coordinates (pixels).
