An interesting feature in the CalTrackAngle suggests that some non-negligible number of events have their cluster direction antimis-aligned with the tracker track . Could we save these events?by 90 degrees. This comes from the fact that when a single crystal is hit in the calorimeter, the CAL axis is set to (0,0,0). When dotted into the TKR direction and taking the arccosine, you are left with 1.57...
