Detailed Description

Normal distribution approximated using linear interpolation.

Parameters of this class are:

NameTypeDefaultRestrictionsDescription
cutoff float0.0  Low intensity cutoff of the model. Peaks below this intensity are not considered part of the model.
interpolation_step float0.1  Sampling rate for the interpolation of the model function
intensity_scaling float1.0  Scaling factor used to adjust the model distribution to the intensities of the data
bounding_box:min float0.0  Lower end of bounding box enclosing the data used to fit the model.
bounding_box:max float1.0  Upper end of bounding box enclosing the data used to fit the model.
statistics:mean float0.0  Centroid position of the model (Gaussian).
statistics:variance float1.0  The variance of the Gaussian.

◆ getCenter()

CoordinateType getCenter ( ) const

get the center of the Gaussian model i.e. the position of the maximum

Reimplemented from InterpolationModel.

assignment operator

◆ setOffset()

void setOffset ( CoordinateType  offset)

set the offset of the model

The whole model will be shifted to the new offset without being computing all over. and without any discrepancy.

Reimplemented from InterpolationModel.

◆ setSamples()

void setSamples ( )
overridevirtual

set sample/supporting points of interpolation

Reimplemented from InterpolationModel.

◆ updateMembers_()

void updateMembers_ ( )
overrideprotectedvirtual

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.
