Detailed Description

BiGaussian distribution fitter (1-dim.) approximated using linear interpolation.

Parameters of this class are:

Name	Type	Default	Description
interpolation_step	float	0.2	Sampling rate for the interpolation of the model function.
tolerance_stdev_bounding_box	float	3.0	Bounding box has range [minimim of data, maximum of data] enlarged by tolerance_stdev_bounding_box times the standard deviation of the data.
statistics:mean	float	1.0	Centroid position of the model.
statistics:variance	float	1.0	The variance 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.
