Detection limits of 3σ for point-like sources near T Tau N in the classical imaging IRDIS mode of VLT/SPHERE and Keck/NIRC2. The bumps in the SPHERE data at ≈250 and ≈600 mas are the wings of the PSF from T Tau N. The Keck/NIRC2 data is obtained from the Keck Observatory Archive, from projects identified as N26N2 for the H-band and 2010B for the K-band data.
