Estimates are from spherical harmonic models CALS10k.1 b (red with
bootstrap uncertainty estimates as dashed lines), CALS3k.4 (blue), CALS7K.2 (grey) and the VGP reconstruction DEFNBKE (black with uncertainty estimates as dashed lines).

As it had turned out that even large - scale features of the model are rather sensitive to changes in the data set, particularly for the earlier part the model, the final model was obtained as the average of 2000 models where data and ages were varied within their
uncertainty estimates and
bootstraps on the final data sets were performed (hence version number 1b).
