In the first paragraph of § 4.4.1 of our recently published manuscript (Blackman & Nauman Reference Blackman and Nauman2015) there is a typographical error that may cause confusion: the $b_{x}$ should be interchanged with $b_{y}$ to match the rest of the text. The corrected paragraph is below:
4.4.1. Tilt angle from fluctuating fields
Because the magnetic stress dominates the Reynolds stress we have, for the box averaged contribution from fluctuations
where $\tan \unicode[STIX]{x1D703}=b_{x}/b_{y}$ , and we assume $|b_{z}/b_{y}|\ll 1$ and $\tan \unicode[STIX]{x1D703}\ll 1$ for the last similarity (justified later).
