Python spherical harmonics function
WebApr 7, 2024 · Triumvirate is a Python/C++ package for measuring the three-point clustering statistics in large-scale structure (LSS) cosmological analyses. Given a catalogue of discrete particles (such as galaxies) with their spatial coordinates, it computes estimators of the multipoles of the three-point correlation function, also known as the bispectrum in Fourier … WebVisualising the spherical harmonics is a little tricky because they are complex and defined in terms of angular co-ordinates, ( θ, ϕ). One way is to plot the real part only on the unit sphere. Matplotlib provides a toolkit for such 3D plots, mplot3d (see Section 7.2.3 of the book and …
