ReadonlykindKind of shape, so that an instance is also a valid Shape1D descriptor.
Calculate the height depending of fwhm and area.
Analytical partial derivatives of fct at x, with respect to x and to
each shape parameter (in the same order as getParameters()). Every shape
provides a closed-form Jacobian, so consumers (e.g. curve fitting) can use
it directly instead of numerical differentiation.
position at which to evaluate the derivatives.
Return a parameterized function of a gaussian shape (see README for equation).
Compute the value of width between the inflection points from Full Width at Half Maximum (FWHM). for more information check the mathworld page
Full Width at Half Maximum.

Calculate the area of a specific shape.
returns the area of the specific shape and parameters.
Calculate intensity array of a gaussian shape.
Intensity values.
Calculate the number of times FWHM allows to reach a specific area coverage.
Optionalarea: numberExpected area to be covered.
Returns an array of the different parameters characterizing the shape
Descriptor of this shape, so JSON.stringify round-trips through getShape1D.
The component widths are emitted rather than fwhm/mu, because they are
the state this shape is defined by: getParameters reports them and
derivative differentiates with respect to them. The effective width and
the mixing ratio are re-derived from them exactly.

fwhm
TCH-style pseudo-Voigt where gaussian and lorentzian widths are independent. The effective fwhm and mixing parameter mu are derived from fwhmG and fwhmL via the Thompson–Cox–Hastings approximation.
