Follow-up Comment #3, bug #22024 (project relax): I have a correction to the statement. The data I added, was for one field. These "rotten chi2 bananas" is to be expected, when only using one field. This behaviour is shown in dx.doi.org/10.1016/j.jmr.2006.01.010 Faithful estimation of dynamics parameters from CPMG relaxation dispersion measurements. Kovrigin, Evgenii L, Kempf, James G, Grey, Michael J, Loria, J Patrick Figure 3, one field. Two fields, figure 6. I making up the script, to show for two fields. _______________________________________________________ Reply to this item at: <http://gna.org/bugs/?22024> _______________________________________________ Message sent via/by Gna! http://gna.org/
