Bispectrum Estimator #236

Open rainwoodman opened 8 years ago

rainwoodman commented 8 years ago

With the new painter features we are one step closer to implementing Marcel's bispectrum estimator.

After brief chatting with Marcel, the algorithm can take three 'field' arguments, each with its own datasource and painters. Field1 and Field2 will be multiplied as RealField, then r2c and multipled with Field3, and pass into the project_to_basis function.

Does there happen to be (even WIP) code lying around for a bispectrum estimator?

rainwoodman commented 2 years ago

On Google search this popped up: https://github.com/sjforeman/bskit

I am not sure if @marcel-sl has any bi-spectrum code prototype developed, but I don't recall I made any progress on this.

Thanks - this looks like it integrates nicely - I will try it out!

I'd also recommend bskit. It should work nicely with nbodykit.
