SHCrossPowerDensityL - Compute the spectral cross-power density of two
real functions for a single degree L.
</PRE>
<H2 class="man">SYNOPSIS</H2 class="man"><PRE>
REAL*8 FUNCTION SHCrossPowerDensityL ( C1, C2, L )
REAL*8 C1(2, L+1, L+1), C2(2, L+1, L+1)
INTEGER L
</PRE>
<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) * C2(i, L+1, m+1) / (2L + 1).
</PRE>
<H2 class="man">ARGUMENTS</H2 class="man"><PRE>
C1 (input) REAL*8, DIMENSION (2, L+1, L+1)
The first function expressed in real spherical harmonics.
C2 (input) REAL*8, DIMENSION (2, L+1, L+1)
The second function expressed in real spherical harmonics.
L (input) INTEGER
The spherical harmonic degree for which the cross power
density will be calculated.
