Line width–size relation for the GMCs in the LMC (filled circles). Triangles show the clouds in the SMC (Mizuno et al. 2001a) and crosses those in the Warp region (Nakagawa et al. 2005); the clouds in these regions are reidentified by using the algorithm described in Rosolowsky & Leroy (2006) and the same parameters used to identify the clouds in the LMC. The thick dashed line is the best‐fitting power law to the GMCs in the LMC, ﹩\Delta V=1.3R^{0.2}﹩, with Spearman rank coefficient of 0.3. The relation found for the GMCs in the inner Galaxy from Solomon et al. (1987, thin dotted line) is shown as an example.
