The authors observed the putative gravitationally lensed images of the quasar, 0957+561, at 13 cm wavelength with a six-antenna VLBI array having nearly milliarcsecond resolution. Using four elliptically shaped Gaussian components to model the observed surface brightness distribution of each of the A and B images, the authors found that the resultant models offer strong evidence in support of the gravitational lens hypothesis. A simple, 2×2 magnification matrix relates quantitatively the brightness distributions of the two "long" jet components in one image to those in the other. The relative image magnification, B/A, is 0.64±0.03 for the two long jet components.
