Running from top to bottom, these figures show the evolution of the sigmoid over three hours leading up to its final eruption. Columns 1 and 2 show results from the St Andrews model. The left column shows the strength of electric current predicted by the model and the central panel shows predictions of temperature. Column 3 shows the development of the sigmoid observed by Hinode. The model successfully predicts the shape of the sigmoid, internal structure and distribution of heat along its length. (Credit: NASA / STFC / ISAS / JAXA / A. Hood (St. Andrews), V.

How exactly did they test the model?

Like with AGW global warming, models are meaningless unless you have real world tests to verify. Otherwise,t hey are just so much math that produces pretty pictures.

I submit like with climate, we do not know how the processes of the sun really work.
