Image Details
Caption: Figure 4.
Reconstructed images for two objects appearing in Table 3. (a) The 692 nm image of HR 463, a fifth-magnitude star that we resolve for the first time in this image. (b) The 880 nm image of HR 463. (c) The 692 nm image of KOI-5822, a star with G = 12.91. (d) The 880 nm image of KOI-5822. A scale bar is shown in the lower portion of panel (b), but applies to all four images, and a yellow arrow shows the location of the secondary star. The 692 and 880 nm images appear as mirror images because the 880 nm channel reflects from the dichroic element in DSSI whereas the 692 nm light is transmitted. The images of KOI-5822 exhibit a feature common to our reconstructions of faint objects, where a low-level peak appears 180° away from the primary at the same separation due to low signal-to-noise phase information in the Fourier plane.
