One comment: the only experimental error information readily available is the noise in the spectrum which can be used as an approximate peak intensity error. Is there any provision to extract noise in the plane of a spectrum in analysis? I know it is a feature of plot2 in the azara suite of programs, so you already have the routines at your disposal. I think having an option to extract the noise will be useful not only for relaxation analysis but for a number of experiments where information is extracted from peak intensity.
