Hi Urs, I am noticing that in the stability plots you show the position of the default value does not correspond to the default result (the only one correct is the Mx scan). Are you sure you have always the default setting in each fit? Daniele > > Hoi, > > in the following are a few links to scans for B, B0 and B+.
