Detailed Description

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

Parameters of this class are:

NameTypeDefaultRestrictionsDescription
interpolation_step float0.2  Sampling rate for the interpolation of the model function.
tolerance_stdev_bounding_box float3.0  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 float1.0  Centroid position of the model.
statistics:variance float1.0  The variance of the model.
statistics:variance1 float1.0  Variance of the first gaussian, used for the lower half of the model.
statistics:variance2 float1.0  Variance of the second gaussian, used for the upper half of the model.
