Correction to: Nature Communications (2019); https://doi.org/10.1038/s41467-018-05883-1; published online 28 August 2018

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 14C 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 14C production in Fig. 1 and Supplementary Table 2 were too high by a factor of 4 × π = 12.566.

As a result of this, the following changes have been made to the originally published version of this Article:

In the original version of Fig. 1, the labels on the colour scale bar were incorrect. The previous incorrect version read, from top to bottom ‘1.40E + 03, 3.25E + 03, 8.00E + 03, 2.70E + 04, 6.00E + 04, 1.50E + 05, 1.75E + 06, 8.50E + 06, 5.25E + 07, 1.80E + 08, 2.29E + 08’. The corrected figure replaces these with, from top to bottom ‘1.11E + 02, 2.59E + 02, 6.37E + 02, 2.15E + 03, 4.77E + 03, 1.19E + 04, 1.39E + 05, 6.76E + 05, 4.18E + 06, 1.43E + 07, 1.82E + 07’.

In the original version of Supplementary Table 2, the values in the second column were incorrect. The correct version of Supplementary Table 2 is:

RC (GV) 14C production (atoms/cm2)
0 1.82E + 07
0.2 1.82E + 07
0.7 1.43E + 07
1.4 4.18E + 06
2.4 6.76E + 05
3.5 1.39E + 05
6.1 1.19E + 04
7.5 4.77E + 03
8.9 2.15E + 03
11.7 6.37E + 02
14.1 2.59E + 02
17.0 1.11E + 02

which replaces the previous incorrect version:

RC (GV) 14C production (atoms/cm2)
0 2.29E + 08
0.2 2.29E + 08
0.7 1.80E + 08
1.4 5.25E + 07
2.4 8.50E + 06
3.5 1.75E + 06
6.1 1.50E + 05
7.5 6.00E + 04
8.9 2.70E + 04
11.7 8.00E + 03
14.1 3.25E + 03
17.0 1.40E + 03

This has been corrected in both the PDF and HTML versions of the Article. This error does not affect the main result, original discussion or conclusions of the Article.
