This post examines runs 6196 (Rarm) and 26783 (Larm). These are ultrathin Carbon runs with sieve out. The A_T plug is unblocked in the Rarm and blocked in the Larm. Figure 1: Rarm focal plane x versus target y (can see the A_T blob) Figure 2: Larm focal plane x versus target y (cannot see the A_T blob) Figure 3: Rarm projected focal plane x vs y with a target y cut around the "a_t blob" Figure 4: Larm projected focal plane x vs y with a target y cut symmetric with the cut made for figure 3. Figure 5: The x projection of figure 3 (Rarm), can see the pronounced A_T event peak precisely where it should be. Figure 6: The x projection of figure 4 (Larm), can see the lack of a A_T event peak.
