SHPowerSpectrumC

Compute the power spectrum of a complex function.

Usage

pspectrum = pyshtools.SHPowerSpectrumC (cilm, [lmax])

Returns

pspectrum : float, dimension (lmax+1)
The power spectrum of the complex function.

Parameters

cilm : complex, dimension (2, lmaxin+1, lmaxin+1)
The complex function expressed in complex spherical harmonics.
lmax : optional, integer, default = lmaxin
The maximum spherical harmonic degree of the power spectrum. This must be less than or equal to lmaxin.

Description

SHPowerSpectrumC will calculate the power spectrum of a complex function expressed in complex spherical harmonics. For a given spherical harmonic degree l, this is calculated as:

pspectrum(l) = Sum_{i=0}^1 Sum_{m=0}^l | cilm[i, l, m] |**2.
