Compute the power spectral density of a complex function for a single spherical harmonic degree.
Usage
psd = SHPowerDensityLC (cilm, l)
Parameters
psd: output, real(dp)- Power spectral density of the complex function for spherical harmonic degree
l. cilm: input, complex(dp), dimension (2,lmaxin+1,lmaxin+1)- The complex function expressed in complex spherical harmonics.
l: input, integer(int32)- 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 4-pi normalized 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).
