The above data are from a shallow core (300 m) drilled at Dye 3, Greenland, in 1986. The data were filtered using a spectral low pass filter with a cut-off of 6 years and interpolated using a cubic spline.
The younger part (1783-1985) has been published in Nature (J. Beer et al., Use of 10Be in polar ice to trace the 11-year cycle of solar activity, Nature 347 (1990) 164-166). 
The whole record appeared in: J.Beer, St.Baumgartner, B.Dittrich-Hannen, J.Hauenstein, P.Kubik, Ch.Lukasczyk, W.Mende, R.Stellmacher and M.Suter, Solar Variability Traced by Cosmogenic Isotopes in The Sun as a Variable Star: Solar and Stellar Irradiance Variations (eds. J.M. Pap, C. Fršhlich, H.S. Hudson and S.K. Solanki), Cambridge University Press, 1994, 291-300.
