Version 4.4
New Slepian expansion routines
SHRotateTapers
for rotating spherical cap Slepian functions, SlepianCoeffs
for expanding a function in a Slepian basis, and SlepianCoeffsToSH
to convert the Slepian coefficients into spherical harmonic coefficients.Slepian
and SlepianCoeffs
for managing Slepian basis functions and the Slepian expansion coefficients of a function.Legendre and spherical harmonic convenience functions
legendre()
to compute all the legendre functions, legendre_lm()
to compute the legendre function for a specified degree and order, spharm()
to compute all the spherical harmonic functions, and spharm_lm()
to compute the spherical harmonic functions for a specific degree and order.Other improvements
SHExpandLSQ
, and added a python wrapped function SHExpandWLSQ()
.min()
and max()
methods to the SHGrid
class, to return the minimum and maximum value of the gridded data.mass
to the SHGravCoeffs
class, which is computed by the input GM and the codata value for G
.omega
to SHGravCoeffs.geoid()
to override the value provided in the class instance.M. A. Wieczorek, M. Meschede, E. Sales de Andrade, I. Oshchepkov, B. Xu, and A. Walker (2018). SHTOOLS: Version 4.4, Zenodo, doi:10.5281/zenodo.592762
