Thanks! This is very helpful!
Is that viewer able to export a 2D map that I can then project onto a sphere in a 3D application though? From the description it sounds like you can view it on a sphere inside the program, but not necessarily export what I'm after.
Thanks again for your help.
Does anyone know how I could convert data from Planck, which appear as an oval shape, into a form that I can easily map onto a sphere (ie. a rectangular shape in 2:1 aspect ratio)?
Here is an example Planck image: http://sci.esa.int/science-e-media/img/61/Planck_CMB_Mollweide_4k.jpg
I see that...
