Algorithm Test: angular power spectrum of tiled cubes #289

Open steven-murray opened 9 months ago

steven-murray commented 9 months ago

To test the algorithm, we should perform a test (and consider making it a unit-test) where we produce a 3D cube with a given power spectrum (using eg. powerbox), tile it onto a healpix map, take the angular power spectrum and compare with the original.

I'll have to dig back to remember how the 3D power spectrum converts to an angular power spectrum.

@steven-murray thanks for keeping track of this. @simonsmatin and I have been working on this, so I would be happy to formalize it and make it an integration test (and add the math/documentation to the repo).

Wonderful, thanks!
