(a) Median NUV−r values are plotted against the normalised SMA/R₂₅ for the control sample of 8 unbarred galaxies. (b) Median NUV−r profiles for the complete sample of barred and unbarred galaxies. (c) Median profile for unbarred galaxies after excluding four internally quenched unbarred galaxies. (d) Profiles of both barred and unbarred samples, after removing the four internally quenched unbarred galaxies. The results show that the inner regions of barred galaxies are quenched within their bar length, whereas unbarred galaxies exhibit comparatively bluer profiles.
