\caption{The unfiltered spectral distribution 
         of the sunshine on Earth
         under the assumption that the Sun is a black body
         with temperature $T = {\rm 5780}\,{\rm K}$
         \textit{and} the unfiltered spectral distribution 
         of the radiation of the ground
         under the assumption that the Earth is a black body
         with temperature $T = {\rm 290}\,{\rm K}$,
