I am confused by the significance of the "a" variable; I understand that we are integrating across all the rays that could contribute to the power of the x' pixel, but I don't see how the "a" variable relates to the equation.

daniel-man the a and r are not explicitly present in the equation but they affect θ′ and θ′′
