Intensity diffraction pattern (linear scale) for the NI2 configuration at λ = 500 nm. Top panels: 2D representations of a zone of 80 × 80 m for the apodized occulter (top panel) and the petal occulter (second panel). Bottom two panels: radial cuts for the angles θ = 0 and θ = π/24. The strong variations for the petal occulter contrast with the smooth variations for the apodized occulter.
