Graph showing the disk radius of each source in the FUV field of the three O stars, θ₁ Ori, σ Ori, and NU Ori. Local extinction has not been taken into account. Systems with detected disks are black and systems without a detected disk are blue. Upper limits for non-detections were derived using the angular size of the coronagraph. Binary systems are indicated with a white marker. No disks are detected at FUV fields higher than ~300 G₀.
