Figure 8
Normalized solar modulation factor and δ 18O record over the last 200 kyr [from Sharma [18]]. The heavy dots correspond to values of the normalized solar modulation factor over the last 200 kyr. Each point is shown with an uncertainty of 1σ standard deviation. Only the y-direction uncertainties are large enough to be seen in the plot.
