Maps of the SO₂ 5_2, 4 − 4_1, 3 transition. Left panel: total intensity map. Right panel: first-moment map for emission above the 4σ noise level in the original data cube. Both maps present contours of the total intensity at 20, 40, 60, and 80% of the peak emission. The input data were restored with uniform weighting of the visibilities, resulting in a synthesized beam of size (shown as white ellipse in the left panel).
