The power of the Cal1ConeCut comes from the fact that the majority of the residual background is sneaking through the bottom of the TKR. The direction of these events is poorly reconstructed since, especially at high energy, the longest straightest track will often come from back-splash. On the other hand, the CAL axis will point along the direction of the incident particle causing the ACD to query the proper tiles.
