(Figure 5) gives a central component with [Sérsic]{} index $n = 1.60$ and effective radius $r_e =$ 137 (693 pc), and a disk with scale length of 386 (1.95 kpc), consistent with the results from the 1-D decomposition of the SDSS $r$-band image. The bulge-like component is mildly disky, with $c = -0.11$. The best-fit parameters are summarized in Table 2. We identify the central $n = 1.60$ component with a pseudobulge, because pseudobulges generally have $n \lesssim 2$ (Kormendy & Kennicutt 2004). The residual image (top right panel of Figure 2) reveals a faint ring-shaped structure on the eastern side of the galaxy, opposite to the masked ring region.

[*HST*]{}: NUV Image
--------------------

The F330W image was observed on 21 March 2003 using ACS/HRC as part of a study on the starburst–AGN connection (Proposal ID: 9379). ACS is located away from the optical axis of [*HST*]{}, and so it suffers from significant geometric distortion that is not corrected by the internal optics. For ease of rejecting cosmic rays, the total exposure was divided into two equal exposures of 10 min each. These images are then combined using [astrodrizzle]{}[^5], a new software replacing [multidrizzle]{}, to remove cosmic ray hits and
