As far as I know this is the angle between the Thrust axis of the Breco
and the Thrust of the rest of the event (Brecoil). As the latter has
changed (i.e. neutral IFR clusters are no longer used) I would expect this
vairiable to change also for charged Breco's.

Yes, I think Ric has just changed the lists used as input for calculation
of the event shape variables, so you still have to use ecalgam > 0 to get
EMC clusters only.
