<p><code>power</code> = SHPowerL (<code>cilm</code>, <code>l</code>)</p>
<h1 id="parameters">Parameters</h1>
<dl>
<dt><code>power</code> : output, real*8</dt>
<dd>Power of the function for a single spherical harmonic degree <code>l</code>.
</dd>
<dt><code>cilm</code> : input, real*8, dimension (2, <code>lmaxin</code>+1, <code>lmaxin</code>+1)</dt>
<dd>The spherical harmonic coefficients of the function.
</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>SHPowerL</code> will calculate the power of a function expressed in real spherical harmonics for a single degree <code>l</code>. This is explicitly calculated as:</p>
<p><code>power = Sum_{i=1}^2 Sum_{m=0}^l cilm(i, l+1, m+1)**2</code> .</p>
