SphericalCapCoef
Calculate the spherical harmonic coefficients of a spherical cap.
Usage
coef
= pyshtools.SphericalCapCoef (theta
, lmax
)
Returns
coef
: float, dimension(lmax
+1)- The zonal spherical harmonic coefficients of a spherical cap centered over the north pole.
Parameters
theta
: float- The angular radius of the spherical cap in radians.
lmax
: integer- The maximum spherical harmonic degree to calculate the spherical harmonic coefficients.
Description
SphericalCapCoef
will calculate the spherical harmonic coefficients of a spherical cap centered over the north pole. The zonal coefficients, returned in the array coef
, are normalized such that the degree-0 term is 1, and are to be used with either the geodesy 4-pi normalized or orthonormalized spherical harmonics.
