 truncate generates <F> and Dano - ie it averages the I+ and I- from
scalepack..

 So if you need to change hand you can reindex within truncate and get
the Dano with the opposite sign. But how can this have happened? I
thought most modern detectors made it impossible to get any indexing
left handed?
