Table 4
Slopes recovered from PCA on the Heyer scaling relation 
.
| Cloud | Ring | Elongated | Concentrated | Clumpy |
|---|---|---|---|---|
| Slope | 3.17 | 4.50 | 3.46 | 3.87 |
| SD | 0.21 | 0.12 | 0.20 | 0.21 |
Notes. The terminology follows Table 3. The expected value of the slope is 1 (Heyer et al. 2009).
