Problem

• The CCA response processor yields the trapping efficiency roughly, but not exactly consistent with the theory or Adil's calculation.

CCA V45 Trap

• Total trapping efficiency by the CCA response: 2.93%
• Total trapping efficiency by Adil's MC: 3.03%

Box Trap

• Total trapping efficiency by the CCA response: 22.36%
• Total trapping efficiency by theory: 22.07%

Harmonic Trap

• Total trapping efficiency by the CCA response: 17.56%
• Total trapping efficiency by theory: 17.53%

Source of the Discrepancy

• is unknown yet.
• Comparing the processor with Adil's calculation code would be helpful to address the issue for the CCA Trap, but not for the box and harmonic traps.
• The field map interpolator method could matter.
