1. Scope 1.1 These tables define the solar constant and zero air mass solar spectral irradiance for use in thermal analysis, thermal balance testing, and other tests of spacecraft and spacecraft components and materials. 1.2 These tables are based upon data from experimental measurements made from high-altitude aircraft, balloons, spacecraft, and the earths surface. The stated accuracies are based on the estimated accuracies of the measurements, calibrations, and radiometric scales.
