I just realised I never dropped a comment on Rheia, despite following (ahem, lurking) the project with interest. But all this is looking really great!

If I wasn't a bit rusty with the climate stuff I might drop some criticisms/suggestions here, but that may have to wait. Btw, did you use MrBragg's methods and attempted to use ExoPlaSim to simulate the climates? Kind of curious what results the software would produce.
