Sorry,that is what I ment,my mistake. Version in my language isn't very helpful since it has only few lines,formulas don't help at all but the picture does.Let's if I got it right-spectral radiance is the density of the radiation,right? So for 5000 K spectral radiance (density) is about 12,5 for...
