Caption: Figure 1.

HST WFC3 F547M images of the AGN host galaxies, displayed with an inverted logarithmic stretch. The black rectangles show the geometry and orientation of each ground-based spectroscopic monitoring aperture. The size of the region displayed is 1′ × 1′, except for NGC 6814 which is displayed in a 2′ × 2′ box. For all images, north is up and east is to the left.
