sft2d.create_grid

sft2d.create_grid(n_theta, n_phi, exclude_poles=True)

Creates a uniform grid in spherical polar coordinates (theta, phi).

Parameters:

• n_theta (int) – Number of grid points in the theta (co-latitude) direction.

• n_phi (int) – Number of grid points in the phi (longitude) direction.

• exclude_poles (bool) – Whether to exclude 5 degrees near the poles. Default is True.

Returns:

A dictionary containing:

• ’theta’: Array of theta values (in radians).

• ’phi’: Array of phi values (in radians).

• ’dtheta’: Spacing in the theta direction (in radians).

• ’dphi’: Spacing in the phi direction (in radians).

Return type:
