Examples of different cloud morphologies. The images are integrated intensity (moment 0) maps of the ¹³CO (2−1) transition. The numbers in the right bottom corner of the images represent the J₁ and the J₂ moments (J plots algorithm), respectively. The colour bars represent the ¹³CO integrated intensity in K kms^–1. The white contours represent the cloud edge. The white circles at the bottom left of the figures represent the telescope beam size.
