[bug #22024] Minimisation space for CR72 is catastrophic. The chi2 surface over dw and pA is bounded. -- May 10, 2014 - 18:29

Follow-up Comment #8, bug #22024 (project relax):

And for this setup, where you have only 1 field, and dw=1.2

Why is it finding a solution under the chi2 surface sheet???



Params for dx map is
['dw', 'pA', 'kex']
Point creating dx map is
[1.2, 0.99299999999999999, 2200.0]
Minimises point in dx map is
[5.5418405143389711, 0.50000101059958624, 0.96403927774135734]
