Effective temperature, bolometric correction, radius, angular diameter and luminosity have been obtained for 9 stars of the spectral type A5-G2, belonging to IV and V liminosity classes, by means of the infrared flux method as modified by Blackwell et al. (1980).The comparison of the effective temperature values with those obtained using the calibration of monochromatic flux by Koornneef for J, K and L bands (Koornneef, 1983) and by Johnson for I, J, K and L bands (Johnson, 1966) shows that Teff in Koornneefs calibration are systematically lower with the difference of the mean values for the stars investigated being about 1.6%. |
