Figure 2.

(Top) Slit diffraction pattern from PSLIT2 recorded by the imager at 936.5 m. (Middle) Horizontal cut through the data (points) and a model (red line) corresponding to a nominal opening of a ₀ = 31.0 µm. (Bottom) Vertical cut through the data (points) and a model (red line) corresponding to a nominal opening of a ₀ = 35.7 µm. Both model calculations use z ₀ = 99 mm; see text.
