Extended emission south of T Tau Sa. Both T Tau Sa and Sb were subtracted using T Tau N as a PSF reference scaled to the peak of T Tau Sa and Sb, respectively. The leftover artefacts are due to the Airy rings apparent around all three components, which cannot be totally eliminated because of the closeness of T Tau Sa and Sb. The leftover residuals have an amplitude of 2.4% and 6.6% of the peak fluxes of T Tau Sa and Sb, respectively.
