Image Details
Caption: Figure 1.
V343 Nor Aa and Ab for the six epochs of imaging data. The top row shows the initial reduced images, the middle row following PSF subtraction of the primary, and the bottom row the results of PSF fitting and subtraction of the secondary. Only two panels are shown for the 2015 July epoch as the secondary PSF was not subtracted. Labels at the top of each column indicate the epoch and the instrument. The best fit orbit (light gray) is indicated in the middle row, as is the derived location of the secondary (+). For the 2009 September and 2016 April epochs a negative of V343 Nor Ab can be seen as the reference PSF was that of V343 Nor rotated by 180°. These negatives do not appear in the final row as the companion was subtracted prior to the subtraction of the primary to create the final image. For the 2015 epoch, the white circle indicates the position and radius of the GPI coronographic mask.
