A drafting error to Figs. 1 and 6 was present in the published paper, which misrepresented the proportion of Na-feldspar in Test Dust 50 (TD50). The error does not affect the results presented in the study, their interpretation, or the conclusions. Correct versions of Figs. 1 and 6 are shown below.
Approximate mineral composition of TD50. Trace minerals (not shown) are kaolinite, illite, and pyrite.
