A comparison between the input model and the two reconstructions at several φ values. In each frame, the greyscale varies linearly from 0–50 mJy/beam, and the contours begin at 50 mJy/beam with a factor of 2 between each level. Left: the model image convolved with an (0.8′′ × 0.8′′ × 40 rad/m2) Gaussian. Middle: the 2+1D reconstruction. Right: the fsimager reconstruction. Top to bottom: φ = −205, − 160, 200, 230, and 395 rad/m2.
