SPANALY

The SPANALY routine analyzes spectral coefficients from Fourier
            coefficients for a latitude pair (Northern and Southern
            Hemispheres).   Vector components are multiplied by cosine
            of latitude.

USAGE:    CALL SPANALY(I,M,IM,IX,NC,NCTOP,KM,WGT,CLAT,PLN,PLNTOP,MP,
                       F,SPC,SPCTOP)

   Input argument list:

      NCTOP    - INTEGER DIMENSION OF SPECTRAL COEFFICIENTS OVER TOP
                 (NCTOP>=2*(M+1))
      KM       - INTEGER NUMBER OF FIELDS
      WGT      - REAL GAUSSIAN WEIGHT
