Image Details
Caption: Figure 2.
PSF-subtracted wavelength-collapsed GPI images of V343 Nor A at the 2015 July 03 epoch displayed in Cartesian coordinates (top row) and projected into polar coordinates centered on the tested location of the companion (bottom row). The three columns correspond to different tested locations of V343 Nor Ab; the adopted astrometry given in Table 1 (left column), the same but with a five degree offset applied on the position angle (middle column), and instead with a 1.5 pixel offset applied on the separation (right column). In the top row, the positions of the two components are indicated by the star symbols. The position of the companion was estimated by maximizing the flux within an annulus centered on the predicted location of the second Airy maximum (central radius of 6 px, and a width of 1 px; white dashed lines), which appears as a rectangular region within the projected images.
