SO-integrated intensity maps over different velocity ranges (indicated at the bottom of each panel in km s^-1). Row 1 shows the transition 3₂−2₁ (E_up = 21.1 K, A_ul = 1.1 × 10^-5 s^-1, S = 1.5). The interval between contours is 8 K km s^-1 and the minimum contour is 15 K km s^-1. Row 2 shows the transition 6₆−5₅ (E_up = 56.5 K, A_ul = 2.2 × 10^-4 s^-1, S = 5.8). The interval between contours is 20 K km s^-1 and the minimum contour is 15 K km s^-1. The white cross indicates the position of the hot core and the black cross the position of the compact ridge.
