Abstract

In my reply I present a re-analysis of the data of the Smithsonian Astrophysical Observatory (SAO). For this, a new data reduction method is introduced, allowing a drastic lowering of data scatter, so that the time series of the reduced data clearly shows the ≈ 1 % variation of the terrestric solar irradiance in parallel with solar activity. The implications are discussed.
