Gaussian spectrum

class gaussian_t : public wt::spectrum::spectrum_real_t

Gaussian (real-valued) spectrum. Uses an analytic truncated Gaussian distribution underneath, providing correct power() queries and sampling facilities.

Public Functions

inline gaussian_t(std::string id, const truncated_gaussian1d_t &dist, const f_t val0, const range_t<wavenumber_t> &range)

gaussian_t(const gaussian_t&) = default

gaussian_t(gaussian_t&&) = default

inline virtual const distribution1d_t *distribution() const noexcept override

Returns the underlying spectrum distribution.

inline virtual f_t power() const noexcept override

Returns the total spectral power contained in this spectrum.

inline virtual f_t power(const range_t<wavenumber_t> &wavenumbers) const noexcept override

Returns the spectral power over the provided wavenumber range.

inline virtual range_t<wavenumber_t> wavenumber_range() const noexcept override

Returns the range of wavenumbers for which this spectrum is defined. Querying the spectrum with wavenumber<range.min or wavenumber>range.max will always be 0.

inline virtual wavenumber_t mean_wavenumber() const noexcept override

Returns the mean wavenumber for this spectrum.

inline virtual f_t f(const wavenumber_t wavenumber) const noexcept override

Query the spectrum. Returns the spectral power for the given wavenumber ‘wavenumber’.
