✦ Synopsis

The conversion of our centre of disk intensities published in 1968/70 into mean disk intensities has been repeated, using more accurate data for the centre-to-limb variation of both continuous radiation and strong absorption lines.

The random observational mean error of the new irradiance data very likely is not larger than 1.5% in the UV and not larger than 1% in the visible and infrared. Comparison with the fluxes of Sun-like stars observed by Hardorp (1980) confirms these errors and seems to exclude the possibility of a systematic, wavelength-dependent scale error which would correspond to a temperature difference larger than 50 K.

The resulting integral value of the irradiance between 0.33 and 1.25 Ix is 1.060, the corresponding value of the solar constant lies between 1.368 and 1.377 kW m -2. * Proceedings of the 14th ESLAB Symposium on Physics of Solar Variations, 16-
