Change Type: Correction
Change Details: The authors became aware of a mistake in the data displayed in Fig. 1 and Supplementary Table 2 of the original version of the Article. Specifically, the <sup>14</sup>C production values were printed out in the code before the conversion between the omnidirectional fluence and the flux. As a consequence, the values of the <sup>14</sup>C production in Fig. 1 and Supplementary Table 2 were too high by a factor of 4×<i>π</i> = 12.566.. As a result of this, a number of changes have been made to both the PDF and the HTML versions of the Article. A full list of these changes is available online.
