Caption: Figure 8.

Keck AO imaging with the vortex coronagraph, showing the edge of the dust cone beautifully. We present both the ADI and RDI images here, and note that the central region is blocked by the coronagraph and is thus better revealed with Keck aperture masking images. The ADI reduction is more sensitive to sharp, faint features, while the RDI image better preserves the smooth, continuum features in the disk. We model the orientation and shape of this dust cone in Section 4.
