	'''Important:''' this is not an inversion tool. Manually inverting a dispersion curve with this tool leads to an extremely poor and biased estimation of the global solution of the inversion problem. ''dinver'' is a much more appropriate inversion tool.		'''Important:''' this is not an inversion tool.
