\tablefoot {The first three columns give the reference to the original work, the wavelength of observation, and the facility used, respectively. In the last two columns we indicate whether the observations spatially separated the northern and southern component and the Sa-Sb sub-components of T~Tau~S, respectively. \\ %\tiny{\textcolor{white}{\citeyear{1999AetA...348..877V}}}}
\tablefoottext {\dag}{Includes also data from WIRO, Keck, and Gemini North. The Sa-Sb pair remained unresolved in most of these observations, ut~several spatially resolved data points are included as well.
