Spots elongations and fields of view without truncation effects for each sequence. The blue circles represent for each sequence the minimum subaperture field of view before the residual error rises to 10 nm more than the full subaperture residual error. The orange triangles correspond to the same field of view projected on the elongation axis of the spots. The red triangles represent the same length renormalised to correspond to a spot seen with a 39 m baseline and observed at zenith. The green circles represent the corresponding field of view for spots rotated by 45° in the subarperture.
