Follow-up Comment #2, bug #21960 (project relax): Actually, it is simply because of the fix for bug #21954. The absolute peak intensity errors are bigger. But this is the same for all data - i.e. the errors are scaled by some factor X. Therefore the optimised parameters are identical, but the final chi-squared values are lower. _______________________________________________________ Reply to this item at: <http://gna.org/bugs/?21960> _______________________________________________ Message sent via/by Gna! http://gna.org/
