The spatially resolved observations of T Tauri binary systems obtained by the authors are listed in Table A.1. Column 1 gives the most common name of the object, Cols. 2 and 3 the wavelength band and the date of observation, Col. 4 the brightness ratio (secondary/primary, usually but not always <1), Cols. 5 through 7 the magnitude of system, primary and secondary components in the respective wavelength band.
Table A.2 contains the adopted near-infrared magnitudes of the components of the young binary systems which compose our sample. The values given here are the mean of all spatially resolved photometric observations, i.e. our data from Table A.1 and measurements published by Chelli et al. (1995), Duchêne (1999a), Ghez et al. (1993, 1997a, 1997b), Haas et al. (1990), Hartigan et al. (1994), Köhler et al. (2000), Moneti & Zinnecker(1991), Richichi et al. (1999), Roddier et al. (1996) and Simon et al. (1992). The values for visual extinction AV and the spectral type given with the primaries, belong to the systems (see Sect. 2.1 for references). The numbers in the last column denote the star forming region: Taurus-Auriga (1), Upper Scorpius (2), ChamaeleonI (3) and Lupus (4).
These two tables are available in electronic form at the CDS only. To demonstrate their contents, very much shortened versions, each containing only a typical one of the first few entries, are given below.
