Integrated intensity maps, in units of K kms^-1, of the ¹²CO(2–1),¹³CO(2-1), and C¹⁸O(2–1) emission (from top to bottom). The ¹³CO(2–1) and C¹⁸O(2–1) maps have a spatial resolution of 30.′2 (corresponding to 0.19 pc at the 1.3 kpc distance of the cloud) and the emission is integrated over the LSR velocity range -12 to 4 kms^-1. The ¹²CO(2–1) map has a spatial resolution of 90° and the emission is integrated over the LSR velocity range -25 to 12 kms^-1. The blue contours trace column densities of 1.8 and 5.0 × 10²² cm^-2 derived from Herschel data (at 36.″3) and are the same in all three panels.
