Distributions of the ratio ESAK(reconstructeded)/ESAK(fit) for three intervals of time. Points summed within intervals (x-axis) of 0.2 and curves smoothed. Dashed curve gives shape of hypothetical distribution of doses according to an estimated maximum standard deviation of 60% in our 1900–1910 dose reconstructions. Dotted curve represents the spread of 20% in doses assumed for 1927–1957
