Analyzes spectral coefficients from Fourier coefficients for a latitude pair (Northern and Southern hemispheres).

Vector components are multiplied by cosine of latitude.

Parameters

I	spectral domain shape (0 for triangular, 1 for rhomboidal)
M	spectral truncation
IM	even number of Fourier coefficients
IX	dimension of Fourier coefficients (IX>=IM+2)
NC	dimension of spectral coefficients (NC>=(M+1)*((I+1)*M+2))
NCTOP	dimension of spectral coefficients over top (NCTOP>=2*(M+1))
KM	number of fields
WGT	Gaussian weight
CLAT	cosine of latitude
PLN	Legendre polynomials
PLNTOP	Legendre polynomial over top
MP	identifiers (0 for scalar, 1 for vector)
F	Fourier coefficients combined
SPC	spectral coefficients
SPCTOP	spectral coefficients over top
