These onaxis effective area curves are simulated by SwiMM.
- No Mask (Blue): The area in the case of removing the mask structure.
- Mask (Magenta): The area in the case of full BAT including the scattring and absorption by the mask tiles.
- Modulated (Green): This area is the actual effective area of BAT. "Modulated" just subtracts the effective area values of "Mask" from "No Mask".
