Compute the power of a complex function for a single spherical harmonic degree.
power = SHPowerLC (cilm, l)
power : output, real(dp)
: Power of the complex function for spherical harmonic degree l.
cilm : input, complex(dp), dimension (2, lmaxin+1, lmaxin+1)
: The complex spherical harmonics of the complex function.
l : input, integer
: The spherical harmonic degree. This must be less than or equal to lmaxin.
SHPowerLC will calculate the power of a complex function expressed in complex 4-pi normalized spherical harmonics for a single spherical harmonic degree l. This is calculated as:
power = Sum_{i=1}^2 Sum_{m=0}^l | cilm(i, l+1, m+1) |**2.
