shxarray.kernels.isokernelbase

class shxarray.kernels.isokernelbase.IsoKernelBase(dsiso=None, name=None, transform=None)

Bases: object

Provides functionality to work with isotropic spherical harmonic kernels

Greensfunc(theta)

Map an isotropic kernel to a 1D Greens function (as a function of distance from the center) :param theta: discretized isotropic distance in degrees :return: A xarray.DataArray with the 1-D Greens function in the spatial domain

attr = {'kernelstate': 'collapsed', 'shtype': 'shiso'}

expanddiag(shindex)

inv()

Returns the inverse of the isotropic Kernel

jacobian(shindex)

name = 'shkernel'

property nmax

property nmin

plot(ax=None, **kwargs)

Plot the isotropic kernel as a function of degree

Parameters:

• ax (matplotlib axis object, optional) – The axis to plot the kernel on. If None, a new axis is created.

• **kwargs (additional keyword arguments for plotting)

Returns:

ax

Return type:

matplotlib axis object

position(lon, lat)

Position this kernel on a specific location of the sphere :param lon: Longitude(s) in degrees of position (list like) :param lat: Latitude(s) in degrees of position (list-like) :return: A xarray.DataArray with the kernel located on the specified locations

transform = None
