!     WNOI       - Array of wavenumbers at the spectral interval

!                  elements long.
!     DWNI       - Array of "delta wavenumber", i.e., the width,
!                  in wavenumbers (cm^-1) of each IR spectral
!                  interval.  NSPECTI elements long.
!     WAVEI      - Array (NSPECTI elements long) of the wavelenght
!                  (in microns) at the center of each IR spectral
!                  interval.
!     WNOV       - Array of wavenumbers at the spectral interval

!     STELLARF   - Array (NSPECTV elements) of stellar flux (W/M^2) in
!                  each spectral interval.  Values are for 1 AU,
!                  scaled to the planetary distance elsewhere.
!     TAURAY     - Array (NSPECTV elements) of the pressure-independent
!                  part of Rayleigh scattering optical depth.
!     TAURAYVAR  - Array (NSPECTV elements) of the pressure-independent
!                  part of Rayleigh scattering optical depth for the variable gas.
!     FZEROI     - Fraction of zeros in the IR CO2 k-coefficients, for
!                  each temperature, pressure, and spectral interval
!     FZEROV     - Fraction of zeros in the VISUAL CO2 k-coefficients, for
!                  each temperature, pressure, and spectral interval
