Detailed Description

@brief BiGaussian distribution approximated using linear interpolation.

Asymmetric distribution realized via two normal distributions with
different variances combined at the mean.

Parameters of this class are:

Name	Type	Default	Description
cutoff	float	0.0	Low intensity cutoff of the model. Peaks below this intensity are not considered part of the model.
interpolation_step	float	0.1	Sampling rate for the interpolation of the model function
intensity_scaling	float	1.0	Scaling factor used to adjust the model distribution to the intensities of the data
bounding_box:min	float	0.0	Lower end of bounding box enclosing the data used to fit the model.
bounding_box:max	float	1.0	Upper end of bounding box enclosing the data used to fit the model.
statistics:mean	float	0.0	Centroid position of the model, this also separates both halves of the model.
statistics:variance1	float	1.0	Variance of the first gaussian, used for the lower half of the model.
statistics:variance2	float	1.0	Variance of the second gaussian, used for the upper half of the model.

Note:

If a section name is documented, the documentation is displayed as tooltip.
Advanced parameter names are italic.

set sample/supporting points of interpolation

Reimplemented from InterpolationModel.

◆ updateMembers_()

void updateMembers_ ( )

This method is used to update extra member variables at the end of the setParameters() method.

Also call it at the end of the derived classes' copy constructor and assignment operator.

The default implementation is empty.

Reimplemented from BaseModel.
