19、he calculations and measurements required far 3.3.2. There ensued a period of gathering further data uch as spectral irradiances, and ultimately all the calculations were carried out. CSfter delays amounting to some years, it was pasible to complete the calculations. Preliminary examination of the d

21、 to abtain the rdlected radiance factors of the intercomparison samples measured by the use of a two-monochromator instrument. These values were used for all the data set5 on the assumption that they represented the most accurate evaluation of this quantity possible. Only one laboratory used an inte
