SHPowerDensityLC
Compute the power spectral density of a complex function for a single spherical harmonic degree.
Usage
psd
= pyshtools.SHPowerDensityLC (cilm
, l
)
Returns
psd
: float- Power spectral density of the complex function for spherical harmonic degree
l
.
Parameters
cilm
: complex, dimension (2,lmaxin
+1,lmaxin
+1)- The complex function expressed in complex spherical harmonics.
l
: 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=0}^1 Sum_{m=0}^l | cilm[i, l, m] |**2 / (2l + 1)
.
