Spherical Harmonics Fortran, SphericalCapCoef will calculate the spherical harmonic coefficients of a spherical cap centered over the north pole. 5 ! 6 SHTools is a time and user-tested open-source archive of both Fortran 95 and Python routines for performing spherical harmonic analyses. SHTns is a high performance library for Spherical Harmonic Transform written in C, aimed at numerical simulation (fluid flows, mhd, ) in spherical geometries. The output data of my spherical, pseudo-spectral simulation has Nr radial levels between rMin and rMax, each Integrals of products of spherical harmonics appear in the evaluation of Coulomb matrix elements in atomic calcu- lations [1,2], and they are closely related to the addition of angular Fortran array indices Fortran arrays usually start with an index of 1. SHTOOLS is a Fortran-95 library that can be used for spherical harmonic transforms, multitaper spectral analyses, expansions of gridded data into Slepian basis functions, and standard operations on global gravitational and magnetic field data. This includes differentiable implementations of the spherical harmonic SHTOOLS/pyshtools is a Fortran-95/Python library that can be used to perform spherical harmonic transforms, multitaper spectral analyses, expansions of functions into Slepian bases, and standard The function expressed in real spherical harmonics. lmax : input, integer (int32) The maximum spherical harmonic degree used in calculating the power spectrum. The zonal coefficients, returned in the array coef, are normalized such that the degree-0 1 program sht_example 2 ! 3 ! This is a modern Fortran example that shows how to set-up the spherical 4 ! harmonic transforms using SHTns. Contribute to gaoyangbi/SH_program development by creating an account on GitHub.
