<p>Compute the power spectral density of a complex function for a single spherical harmonic degree.</p>
<h1 id="usage">Usage</h1>
<p><code>psd</code> = SHPowerDensityLC (<code>cilm</code>, <code>l</code>)</p>
<h1 id="parameters">Parameters</h1>
<dl>
<dt><code>psd</code> : output, real*8</dt>
<dd>Power spectral density of the complex function for spherical harmonic degree <code>l</code>.
</dd>
<dt><code>cilm</code> : input, complex*16, dimension (2, <code>lmaxin</code>+1, <code>lmaxin</code>+1)</dt>
<dd>The complex function expressed in complex spherical harmonics.
</dd>
<dt><code>l</code> : input, integer</dt>
<dd>The spherical harmonic degree. This must be less than or equal to <code>lmaxin</code>.
</dd>
</dl>
<h1 id="description">Description</h1>
<p><code>SHPowerDensityLC</code> will calculate the power spectral density of a complex function expressed in complex 4-pi normalized spherical harmonics for a single spherical harmonic degree <code>l</code>. This is calculated as:</p>
<p><code>psd = Sum_{i=1}^2 Sum_{m=0}^l | cilm(i, l+1, m+1) |**2 / (2l + 1)</code>.</p>
