The results of the first observational programme of the stellar intensity interferometer at Narrabri are presented. The measurements are analysed to yield the angular diameters of 15 stars. The results are used to derive the absolute monochromatic flux ( Fλ ) at the surface of these stars. These values of Fλ are then used to calibrate the line blanketed theoretical model stellar atmospheres of Mihalas to find the effective temperatures ( T e ). A scale of effective temperature for stars in the spectral range Bo to G2, excluding supergiants, is derived. It is believed that this scale represents an improvement on previous temperature scales.
