Table 1 The vertical stretch and scaled area of images from gravitationally lensed sources. The coordinate distance \(s = r_f \theta\) is the distance from the optical axis in the source plane in billions of years. The choice of three source positions shows three horizontal cuts of Fig. 1. An image with no distortion would have stretch and area values of 1. Stretch greater than one indicates the image is stretched perpendicular to the line connecting the optical axis and source.
