Top row: absolute value of jointly time and direction-dependent gain of antenna 0 (same as Fig. 9) restricted to sky region with significant flux. Bottom: fit of the antenna gain resulting from pointing errors to the reconstructed gain in the top row. Except for minor differences, the gains resulting from pointing errors can reproduce the reconstructed gains. The offset fit to the nominal pointing direction is specified as δx and δy. As Cygnus A is less extended in y-direction than in x-direction, the gains are much less sensitive to pointing offsets in y-direction.
