Abstract
The following characteristics of solar radiation in the spectral range from X-rays at 0.1 nm to the millimeter radio waves are given: spectral flux distributions in energy units at the 1 AU distance from the Sun, spectral radiance of the center of the solar disk, mean spectral radiance of the solar disk, limb darkening and blanketing coefficients.The most recent data have been taken into account.In comparison with our monograph (Makarova et al. 1991), the data are given with smaller wavelength steps and averaging bins.Since the fluxes in the far ultraviolet and X-ray ranges depend on the activity level, in the wavelengths <120 nm we present the data for the minimum and maximum of solar activity.
