fixed points in harmonic RGSpace
When looking at _hermitianize_correct_variance in rg_space.py, I wondered whether the determination of fixed points is correct. Assuming a 1D case, the code determines two fixed points: one at 0, and one at N/2. But as far as I understand, the one at N/2 is only a fixed point if N is an even number.
Please let me know if I'm confusing different things here!
