Hi Djam, thanks for the plots. I think that you can see from your first plot the problem I was bithcing about. Namely, the FFS and BFS are misaligned. I think one workaround is to run SetGeometryFiles -f 6, look at the result, find the angle of T2, and then run SetGeometryFiles -f 6 -g <t2 angle> . I will check this with the cool new drawGeo.C to find out if I am correct.
