Left: ADI image of θ Boo obtained with LMIRCam after processing with the LEECH-survey pipeline. The image has a FOV of 4″. A central mask of 5λ/D radius is used to improve the visualization. No feature indicating the presence of a companion is detected between 0.3″ and 4". Right: ADI image of θ Boo from SHARK-NIR after processing with the SHARP pipeline using five PCA components. The image has a FOV of 1.3″. For both images, the outer circle indicates the coherent FOV of NOMIC in the N′-band (~670 mas; see Eq. (1)), and the inner dashed circle represents the EEID (~ 138 mas). No feature indicating the presence of a companion is detected between 0.15″ and 1.3″.
