Notes. The parameters are the effective temperature Teff in K, the gravity log g in cm/s2, the microturbulent velocity ξt in km s-1, the metallicity [Fe/H], the abundances of carbon, nitrogen, and oxygen, the 12C/13C-ratio and the photospheric stellar angular diameter θd in milliarcseconds. The calculation of the angular diameter is discussed in Sect. 4. The table also contains the distances (in pc) and the values of the interstellar extinction Av as derived from the model of Arenou et al. (1992) and the K-band magnitude used for the absolute calibration of the SEDs. Values, for which no literature values have been found, have been assumed on the basis of analogue objects, and are listed in italics.
