see M. Stuiver, P. J. Reimer and T. F. Braziunas: "High-Precision Radiocarbon Age Calibration for Terrestrial and Marine Samples." In: Radiocarbon 40, 1127-1151 (1998). doi:10.1017/S0033822200019172.
The time range of –1000 to 1950 has been chosen so that deviation of radiocarbon age from calendar age (the straight line), non-linear variations of the radiocarbon age and several purported clusters of De Vries Cycles would be visible. (For hypothesized De Vries cycles, see e.g. Ilya Usoskin, Kalevi Mursula: "Grand Minima and Maxima of Solar Activity."
