An example of an L-CPSB galaxy with ﹩\mathrm{log}({M}_{* }/{M}_{\odot })=9.37﹩. Panel (a) displays the SDSS g, r, i image. Panel (b) shows the D_n4000 map, where bluer colors indicate smaller values and redder colors indicate larger values, ranging from 1.0 to 1.8. Panel (c) displays PSB spaxels in red, spaxels of median spectral S/N > 10 per pixel in blue, lower-S/N spaxels in gray, and outlines the PSB region defined by Z. Cheng et al. (2024) in yellow. Panel (d) presents the W(Hα)–Hδ_A diagram, where the central spaxel is marked by a red star, PSB spaxels are in red, and other spaxels with median spectral S/N per pixel >10 are in blue. Panel (e) shows the central spectrum, with the observed flux in black and the best-fit stellar continuum model in red. The MaNGA ID of the galaxy is labeled at the bottom right.
