SHPowerDensityLC
Compute the power spectral density of a complex function for a single spherical harmonic degree.
Usage
psd
= SHPowerDensityLC (cilm
, l
)
Parameters
psd
: output, real*8- Power spectral density of the complex function for spherical harmonic degree
l
. cilm
: input, complex*16, dimension (2,lmaxin
+1,lmaxin
+1)- The complex function expressed in complex spherical harmonics.
l
: input, integer- The spherical harmonic degree. This must be less than or equal to
lmaxin
.
Description
SHPowerDensityLC
will calculate the power spectral density of a complex function expressed in complex spherical harmonics for a single spherical harmonic degree l
. This is calculated as:
psd = Sum_{i=1}^2 Sum_{m=0}^l | cilm(i, l+1, m+1) |**2 / (2l + 1)
