Table 8: Absolute parameters for V781 Tau. All uncertainties are standard errors except for the temperatures as explained in the caption to Table 6. J is the orbital angular momentum in units of 1052 g cm2 s-1and j is the angular momentum per unit of reduced mass in units of 1018 cm2 s-1. Star 1 is eclipsed at primary minimum (phase 0 $.\!\!^{\scriptscriptstyle\rm p}$0).
