<h1 id="description">Description</h1>
<p><code>SphericalCapCoef</code> will calculate the spherical harmonic coefficients of a spherical cap centered over the north pole. The zonal coefficients, returned in the array <code>coef</code>, are normalized such that the degree-0 term is 1, and are to be used with either the geodesy 4-pi normalized or orthonormalized spherical harmonics.</p>
