SHMagPowerL - Compute the power of the magnetic field for a single
degree L given the Schmidt seminormalized magnetic
potential spherical harmonic coefficients.
</PRE>
<H2 class="man">SYNOPSIS</H2 class="man"><PRE>
REAL*8 FUNCTION SHMagPowerL ( C, A, R, L )
REAL*8 C(2, L+1, L+1), A, R
INTEGER L
</PRE>
<H2 class="man">DESCRIPTION</H2 class="man"><PRE>
<B>SHMagPowerL</B> will calculate the power of the magnetic field at radius R
for a single degree L given the magnetic potential Schmidt
seminormalized spherical harmonic coefficients C evaluated at radius A.
This is explicitly calculated as:
(L+1) (A/R)**(2L+4) Sum_{m=0}^L [ C(1, L+1, m+1)**2 + C(2, L+1, m+1)**2 ].
</PRE>
<H2 class="man">ARGUMENTS</H2 class="man"><PRE>
C (input) REAL*8, DIMENSION (2, L+1, L+1)
The Schmidt seminormalized spherical harmonic coefficients of
the magnetic potential.
A (input) REAL*8
The reference radius of the magnetic potential spherical
harmonic coefficients.
R (input) REAL*8
The radius to evaluate the magnetic field.
L (input) INTEGER
The spherical harmonic degree for which the power will be
calculated.
