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