Fig. 2

image

Example of the high-contrast final image of a SPOTS target first observed with NaCo in H band (left panel) and later followed up with SPHERE (right panel, H2 filter (λH2 = 1.593 μm) in the dual-band IRDIS mode). The binary star is unresolved at the center of each image and its halo of diffracted light has been suppressed with the LOCI and PCA/KLIP algorithms, respectively. The figure shows the HIP 69781 system in a linear scale spanning ± 6 × 10−6 times the primary flux. The presence of 6 CCs is revealed in both epochs, which were assigned background motion from astrometric analysis.
