Fig. 5.


Maps of for the features S1, S2a/b, S3, and S4 with the same logarithmic color scale applied to all images. The velocity range is given in the bottom right corner and was chosen based on the velocity range of the features in Fig. 4. The background shows the continuum map with contours beginning at 3σ VLBI and increasing logarithmically by a factor of two. The gray circle in the lower left corner depicts the synthesized beam.
