Caption: Figure 20.

(A) ACS discovery image (Kalas et al. 2006, cf. Figure 1) with IWA_effective r = 3 farcs 0 digital mask. (B) STIS five-roll combined PSFTSC image. Same image scale as panel (A). Improves IWA_effective by ×10 to IWA_minimum = 0 farcs 3 (5.4 AU projected; small yellow circle). 400 × 400 STIS pixels, log₁₀ display [−2.2] to [+1.5] {dex} counts s⁻¹ pixel⁻¹. (C) "Inner" disk undetectable with ACS observed with STIS, at two times the spatial scale with respect to panel (B) (same data); 200 × 20 pixels (11 farcs 54 × 11 farcs 54), log₁₀ display [−1.5] to [+1.5] {dex} counts s⁻¹ pixel⁻¹. All images north up, east left.
