.. _auto_gaussian_spectrum_generator:

*GAUSSIAN SPECTRUM GENERATOR*
=============================

Generates a set of Prony Gi/βi terms by sampling a Gaussian relaxation spectrum defined by 5 parameters (amplitude, mean in ln(β), width/σ, point spacing, skew). Used standalone or as the term generator inside the Prony Series Generator's Gaussian fitting mode.
