...$\alpha_{\rm D}$-effect

Note that the parameter $\alpha_{\rm D}$ of the dynamo theory, considered in this section, in Sect. 5, and in Appendix B, is conceptually different from the parameter $\alpha$ characterizing a force-free coronal field in Sects. 2 and 3. Therefore, we mark it with the subscript D to avoid any confusion.
