Table 5: Chronology Development scores. Detrending method 1 = RCS (and Signal Free), and 2 = individual detrending. Age range is the difference between highest and lowest point on the mean age curve over the past millennium. Age trend is the slope of a linear regression fit to the mean age curve over the past millennium (times 100). Maximum frequency indicates the wavelength of lowest frequency information retained in a reconstruction including 1 = multi-centennial, 2 = centennial, and 3 = decadal. Values in red are estimates.
