Examples of four randomly chosen composite (bulge + disk) galaxies from our sample of MaNGA central galaxies. Each panel shows the pseudo-V-band flux (in normalised units), with a white star indicating the centre of the galaxy. Overlaid on each galaxy flux map is the bulge effective radius (R_b, inner black circle), 2 × the bulge effective radius (outer black circle), and the elliptical half light radius (R_e) of the galaxy as a whole (white ellipse). The SDSS object ID is provided as a title on each panel. In MaNGA, we define bulge spaxels to reside at r < R_b and disk spaxels to reside at r > 2 R_b, leaving a buffer zone where contamination from both components is likely high.
