Gaussian process regression for density profile reconstruction from interferometry and reflectometry measurements

Abstract : Objective: development of the WEST data pre-processing tool using Bayesian methods for fitting the density profiles. Complete reconstruction of density profiles using interferometry and reflectometer measurements. Study the L-H transitions in the shot for a better understanding of physics behind pedestal Summary: Development of a user friendly function that deals with most profiles. Fitting and saving for $n_e$ from mixing btw reflectometer and interferometer. Possible L-H transition was observed in the shot 55564 and the formation of the pedestal is shown
