Left and middle panels: dependence of the dust mass and IR luminosity on the 350 μm monochromatic luminosity. Symbol colors show the temperature of the cold dust component, and the blue line shows the best fit. The typical error is shown by the black cross. Equivalent figures for monochromatic luminosities at 550 μm and 850 μm can be found in Appendices E and F. Right panel: correlation between the temperature of the cold dust component and the 100 μm to 350 μm flux ratio, with the best fit shown by the dashed blue line. Large, red crosses show the mean value of T_cold in 0.5 mag color bins, and the red dashed curve corresponds to the best fit line to the red crosses. The typical error in the x-axis is shown by the black horizontal line. Similar plots relating T_cold to IR and sub-mm colors can be found in Appendix D. In all panels the symbols are the same as in Fig. 10.
