This project has been funded by the priority program 1573 “Physics of the interstellar medium” of the German Science Foundation. Using yt \citep{2011ApJS..192....9T}¹ made analysing the simulated data a great deal more efficient and painless than it otherwise would have been. NM sincerely thanks the development team for their rapid resolution of problems and squashing of bugs. In parts of this work we made use of Astropy², a community-developed core Python package for Astronomy \citep{2013A&A...558A..33A}.
