We combine the new positions with recalibrated NACO-measurements and data from the literature. Model fits for the orbits of T Tau Sa and Sb around each other and around T Tau N yield orbital elements and individual masses of the stars Sa and Sb.\n  Our new orbit for T Tau Sa/Sb is in good agreement with other recent results, which indicates that enough of the o","authors_text":"G.
