sd_gaussian_fwhm
(peak_wavelength, fwhm, shape=SpectralShape(360, 780, 1), **kwargs)[source]¶ Returns a gaussian spectral distribution of given spectral shape at given peak wavelength and full width at half maximum.
- Parameters
peak_wavelength (numeric) – Wavelength the gaussian spectral distribution will peak at.
fwhm (numeric) – Full width at half maximum, i.e. width of the gaussian spectral distribution measured between those points on the y axis which are half the maximum amplitude.
shape (SpectralShape, optional) – Spectral shape used to create the spectral distribution.
- Other Parameters
**kwargs (dict, optional) – {
colour.SpectralDistribution
}, Please refer to the documentation of the previously listed class.- Returns
Gaussian spectral distribution.
- Return type
Notes
By default, the spectral distribution will use the shape given by
colour.SPECTRAL_SHAPE_DEFAULT
attribute.
