BayesStretch2 v1¶
Summary¶
Creates a grid showing the variation of a stretched exponential function for different FWHM and beta values.

Description¶
This is a variation of the stretched exponential option of Quasi. For each spectrum a fit is performed for a grid of \(\beta\) a FWHM values. The unnormalised probability is given for the \(z\) values.
This routine replaces the BayesStretch algorithm.
