Line-integrated intensity map of C¹⁸O (2 - 1), SO (6₅ - 5₄), and SO₂ (4_2,2 - 3_1,3) of the IRAM 30 m data (left) and merged or NOEMA data (right). The line-integrated intensity is shown in color in all panels. The contours and arrows are the same as in Fig. 1. The synthesized beam of the line and continuum data is shown in the bottom left and right corners, respectively. The scale bars are shown in the top left corner in all panels. In the right panels, distinct structures (bridge and stick) seen in molecular emission are indicated by dashed ellipses.
