Description
Version 4.4
New Slepian expansion routines
- Added the new Fortran 95 functions
SHRotateTapers
for rotating spherical cap Slepian functions,SlepianCoeffs
for expanding a function in a Slepian basis, andSlepianCoeffsToSH
to convert the Slepian coefficients into spherical harmonic coefficients. - Added two python classes
Slepian
andSlepianCoeffs
for managing Slepian basis functions and the Slepian expansion coefficients of a function.
Legendre and spherical harmonic convenience functions
- Added 4 python convenience functions for computing Legendre and spherical harmonic 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, andspharm_lm()
to compute the spherical harmonic functions for a specific degree and order.
Other improvements
- Added the option to perform a weighted least squares inversion in the fortran routine
SHExpandLSQ
, and added a python wrapped functionSHExpandWLSQ()
. - Added
min()
andmax()
methods to theSHGrid
class, to return the minimum and maximum value of the gridded data. - Added the property
mass
to theSHGravCoeffs
class, which is computed by the input GM and the codata value forG
. - Add the optional parameter
omega
toSHGravCoeffs.geoid()
to override the value provided in the class instance. - Fixed some minor typos and usability issues, and cleaned up the python wrapper and signature files.
