Things to remember

Remember that the Arrow display (p. 30) has different color scale and check that you are using the same color map (p. 21) in different windows.

Remember also, that because the estimation method tries to minimize the current, the absolute scale of the estimate is very likely smaller than that of the real current. However, the relative strengths at different time points or measurements should be reasonable.
