SHPowerDensityL
Compute the power spectral density of a real function for a single spherical harmonic degree.
Usage
psd
= pyshtools.SHPowerDensityL (cilm
, l
)
Returns
psd
: float- Power spectral density of the function for the spherical harmonic degree
l
.
Parameters
cilm
: float, dimension (2,lmaxin
+1,lmaxin
+1)- The function expressed in real spherical harmonics.
l
: integer- The spherical harmonic degree.
Description
SHPowerDensityL
will calculate the power spectral density of a function expressed in real spherical harmonics for a single degree l
. This is explicitly calculated as:
psd = Sum_{i=0}^1 Sum_{m=0}^l cilm[i, l, m]**2 / (2l + 1)
.
