Erratum for: A&A 623, A30 (2019) https://doi.org/10.1051/0004-6361/201834718

This is an erratum for Widmark (2019), with two corrections to the text in the article.

Firstly, in the bottom row and second column of Table 3 of the article, there is a numerical range that reads 6.3–6.3, which should instead read 6.0–6.3.

Secondly, the matrix elements of Eq. (21) all contain a factor of k_μ/ϖ. These factors should really be squared, such that the equation reads

$$\begin{array}{c}\hfill {\stackrel{\sim }{\mathbf{\Sigma }}}_{\mu }=\left[\begin{array}{cc}{\left({\displaystyle \frac{k_{\mu }}{\varpi }}\right)}^2{\widehat{\sigma }}_{{\mu }_l}^2(1-{\widehat{\rho }}_{\varpi {\mu }_l}^2)& {\left({\displaystyle \frac{k_{\mu }}{\varpi }}\right)}^2{\widehat{\sigma }}_{{\mu }_l}{\widehat{\sigma }}_{{\mu }_b}({\widehat{\rho }}_{{\mu }_l{\mu }_b}-{\widehat{\rho }}_{\varpi {\mu }_l}{\widehat{\rho }}_{\varpi {\mu }_b})\\ {\left({\displaystyle \frac{k_{\mu }}{\varpi }}\right)}^2{\widehat{\sigma }}_{{\mu }_l}{\widehat{\sigma }}_{{\mu }_b}({\widehat{\rho }}_{{\mu }_l{\mu }_b}-{\widehat{\rho }}_{\varpi {\mu }_l}{\widehat{\rho }}_{\varpi {\mu }_b})& {\left({\displaystyle \frac{k_{\mu }}{\varpi }}\right)}^2{\widehat{\sigma }}_{{\mu }_b}^2(1-{\widehat{\rho }}_{\varpi {\mu }_b}^2)\end{array}\right].\end{array}$$(21)

These corrections apply only to the text in the article. In the analysis, the correct numbers and expressions are used, so the results of Widmark (2019) are not affected.
