Detection limits for companions around θ Boo in the L′-band with LMIRCam (left) and in the H-band with SHARK-NIR (right). The blue line shows the contrast as a function of angular separation. For four contrast levels, the corresponding detection limit is given in terms of mass (in units of Jupiter mass). The best mass constraint is obtained in the H-band around 1″, with a limit of 11 M_Jup. The system is assumed to be 500 Myr for these mass constraints.
