Clette, Frédéric; Svalgaard, Leif; Vaquero, José M.; Cliver, Edward W. “Revisiting the Sunspot Number”. 《Space Science Reviews》 186 (1-4): 35–103. arXiv:1407.3231. doi:10.1007/s11214-014-0074-2. ISSN 0038-6308. On average, the observed sunspot number after 1945 is a factor 1.21 higher than the expected value, again showing the influence of the weighting of sunspots according to size, coinciding with the tenure of Waldmeier
