SHPowerSpectrumC
Compute the power spectrum of a complex function.
Usage
pspectrum
= pyshtools.SHPowerSpectrumC (cilm
, [lmax
])
Returns
pspectrum
: float, dimension (lmax
+1)- The power spectrum of the complex function.
Parameters
cilm
: complex, dimension (2,lmaxin
+1,lmaxin
+1)- The complex function expressed in complex spherical harmonics.
lmax
: optional, integer, default =lmaxin
- The maximum spherical harmonic degree of the power spectrum. This must be less than or equal to
lmaxin
.
Description
SHPowerSpectrumC
will calculate the power spectrum of a complex function expressed in complex spherical harmonics. For a given spherical harmonic degree l
, this is calculated as:
pspectrum(l) = Sum_{i=0}^1 Sum_{m=0}^l | cilm[i, l, m] |**2
.
