Detailed Description

Exponentially modified gaussian distribution model for elution profiles.

Parameters of this class are:

Name	Type	Default	Description
cutoff	float	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	Scaling factor used to adjust the model distribution to the intensities of the data
bounding_box:min	float	0	Lower end of bounding box enclosing the data used to fit the model.
bounding_box:max	float	1	Upper end of bounding box enclosing the data used to fit the model.
statistics:mean	float	0	Centroid position of the model.
statistics:variance	float	1	The variance of the model.
emg:height	float	100000	Height of the exponentially modified Gaussian.
emg:width	float	5	Width of the exponentially modified Gaussian.
emg:symmetry	float	5	Symmetry of the exponentially modified Gaussian.
emg:retention	float	1200	Retention time of the exponentially modified Gaussian.
