SO₂-integrated intensity maps over different velocity ranges (indicated at the bottom of each panel in km s^-1). Row 1 shows the transition 4_(2,2)−3_(1,3) (energy E_up = 19 K, Einstein coefficient A_ul = 7.7 × 10^-5 s^-1, and line strength S = 1.7), row 2 the transition 11_(1,11)−10_(0,10) (E_up = 60.4 K, A_ul = 1.1 × 10^-4 s^-1, S = 7.7), and the last row shows the transition 14_(3,11)−14_(2,12) (E_up = 119 K, A_ul = 1.1 × 10^-4 s^-1, S = 8.1). The interval between contours is 10 K km s^-1, the minimum contour is 5 K km s^-1 and the maximum 155 K km s^-1. The white cross indicates the position of the hot core and the black cross the position of the compact ridge.
