Top: 1.4 mm continuum maps of SVS13 A using A configuration (left) and A+C (right). Contours start at 3σ and 10σ respectively, and increase by 10σ. Crosses show the positions of VLA4B and VLA4A, corrected for our proper motions (Appendix A). The synthesized beam is plotted in the bottom left corner. Bottom: residuals after removal of a point source fit to the A config. uv-data at the position of VLA4A. The color scale is in mJy/beam.
