Data structures for working along the spectral dimension.

Spectral grid

SpectralGrid()	Abstract interface for all spectral grids.
MonoSpectralGrid(wavelengths)	A spectral grid consisting of discrete wavelengths, used in monochromatic modes.
CKDSpectralGrid(wmins, wmaxs[, wcenters, ...])	A spectral grid that splits the spectral dimensions into bins characterized by their bounds.

Spectral response functions

SpectralResponseFunction()	An interface defining the spectral response function of an instrument.
UniformSRF([wmin, wmax, value])	A spectral response function uniform on a preset spectral interval.
BandSRF(wavelengths, values)	The spectral response function for a single band of an instrument.
DeltaSRF(wavelengths)	A spectral response function consisting of multiple Dirac delta distributions.

Spectral response utilities

response.make_gaussian(wl_center, fwhm[, ...])

Generate a Gaussian spectral response function dataset from central wavelength and full width at half maximum values.

Spectral indexes

SpectralIndex()	Abstract spectral index base class.
MonoSpectralIndex([w])	Monochromatic spectral index.
CKDSpectralIndex([w, g])	CKD spectral index.

CKD spectral quadrature specification strategies

CKDQuadConfig([type, ng_max, policy])	This class holds configuration parameters for a CKD quadrature rule.
CKDQuadPolicy(value)	This enumeration defines flags mapping to policies defining the number of CKD spectral quadrature points for a given spectral bin.
