Position–velocity plots of [C II], [O I], and ¹³CO(2–1) in contours enhanced with gray-scale along cuts shown in Fig. 2. The zero position for the NW-SE cut (top panels) is at (+27′′,−23″. 5) and for the NE-SW cut (bottom panels) at (−27′′,+10′′), relative to the map center. For each cut we plotted 10 contours. For [C II] these go from 1.4 K to peak temperature. For [O I] and ¹³CO(2–1) the lowest contours are 3 and 0.4 K, respectively. The gray-scale goes from zero to 1.5 times the peak temperature. For all cuts we drew the position of the PDR rims (as seen in 8 μm IRAC image) with a dotted line, as well as the position of the ionizing star, CPD −59°2661. The rims and the O star are labeled in the middle panel. In the NE-SW cut the dotted line labeled “neck” indicates the middle of the duck neck.
