In the version of this Article originally published, the first sentence of the Acknowledgements “We would like to thank D. Papale, M. Zapparoli, L. Portoghesi, M. di Porcia e Brugnera, and H. Verbeeck for feedback that helped improve the manuscript.” should have been “We would like to thank: F. Berzaghi's PhD thesis committee: D. Papale, M. Zapparoli and L. Portoghesi; A. Swann and S. Wasser for their conception of this idea and their mentorship during the initial work on the project; and M. di Porcia e Brugnera and H. Verbeeck for feedback that helped improve the manuscript.” This has now been amended.
