Same colours as in Fig. 10. Correlation of the estimated dust mass, M_dust with the UV slope, β_FUV. The correlation with β_FUV alone accounts for 44% of this variation, which confirms that the spectral information on lines is the most important one. The other tested parameters – metallicity (about 2%) and redshift (<1%) – as well as the level of the sub-millimetre upper limits, are not significantly correlated with M_dust in this analysis.
