Notes. The first column gives the name of the observed cloud, the second column the value of the visual extinction at the centre of the cloud, the third column the visual extinction around the cloud (extinction of the incident radiation field), the fourth column the lowest colour temperature measured in the cloud, the fifth column indicates whether the submillimetre emission of big grains is enhanced towards the cloud centre, the sixth column shows whether an anti-correlation between the emissivity spectral index and the colour temperature is observed, and the last column indicates the corresponding references.
