uv coverage dispersed in wavelength of the observations acquired during the programs 080.D-0231 (grey-scale), and 084.D-0361 (red-scale). The colour code ranges from 8–12.5 μm, with light colours indicating shorter wavelengths. The sample is restricted to the observations used for this work (marked with (b) and (d) in Table 1).
