<H2 class="man">DESCRIPTION</H2 class="man"><PRE>
       <B>SHCrossPowerDensityL</B> will calculate the spectral cross-power density of
       two functions expressed in real spherical harmonics for a single degree
       L. This is explicitly calculated as:

       Sum_{i=1}^2 Sum_{m=0}^L C1(i, L+1, m+1)
