a) Velocity-integrated intensity map of [C ii] in color and contors. The contor levels are at 79 to 339.4   K km s^-1 (peak) in steps of 29  K km s^-1. b) Integrated intensity map of CO 11–10 (color) overlayed with contors of CO 13–12 (white) and [C ii] (black) intensities. Contour levels for CO 13–12 are: 2.1 to 11.7  K km s^-1 (peak). v_LSR-range of integration is [C ii]: [ − 20; − 5], CO: [ − 16; − 11]  km s^-1. The white star denotes the B1 star at (α;δ) = (22^h57^m6.2^s;62°37′55.4″). Offsets of the marked CO peaks #1, #2, and #3 are ( − 45′′, +64′′), ( − 41′′, +20′′), and ( − 9′′, +3′′), respectively.
