SHPowerLC

Compute the power of a complex function for a single spherical harmonic degree.

Usage

power = SHPowerLC (cilm, l)

Parameters

power : output, real*8
Power of the complex function for spherical harmonic degree l.
cilm : input, complex*16, dimension (2, lmaxin+1, lmaxin+1)
The complex spherical harmonics of the complex function.
l : input, integer
The spherical harmonic degree. This must be less than or equal to lmaxin.

Description

SHPowerLC will calculate the power of a complex function expressed in complex spherical harmonics for a single spherical harmonic degree l. This is calculated as:

power = Sum_{i=1}^2 Sum_{m=0}^l | cilm(i, l+1, m+1) |**2.
