Table 6: Derived dereddened magnitudes and colors for the $\theta ^1$Ori C components. For the photometry of the total system, we used data from Hillenbrand et al. (1998, J=4.63, H=4.48, K=4.41) and Hillenbrand (1997, V=5.12). An extinction of AV=1.74 (Hillenbrand 1997) was assumed (using the reddening law by Mathis 1990 and, similar to Mathis & Wallenhorst 1981, a high RV=5.0).
