Detailed Description

@brief Extended isotope distribution approximated using linear interpolation.

This models a smoothed (widened) distribution, i.e. can be used to sample actual raw peaks (depending on the points you query). If you only want the distribution (no widening), use either EmpiricalFormula::getIsotopeDistribution() // for a certain sum formula or IsotopeDistribution::estimateFromPeptideWeight (double average_weight) // for averagine

Peak widening is achieved by a Gaussian shape.

◆ setOffset()

void setOffset ( CoordinateType offset )

overridevirtual

set the offset of the model

The whole model will be shifted to the new offset without being computing all over. This leaves a discrepancy which is minor in small shifts (i.e. shifting by one or two standard deviations) but can get significant otherwise. In that case use setParameters() which enforces a recomputation of the model.

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.
