Spectral energy distribution (SED) of CB230. The data shown are the SCUBA-2 measurements at 450 and 850 μm (corrected for CO(3–2)-emission), the integrated flux at 1.3 mm (Launhardt et al. 2010), and the Herschel data points at 70, 100, 160, 250, 350 and 500 μm (extracted from Fig. 4 in Launhardt et al. 2013). The fit to the data (red) was obtained by assuming a dust optical depth at 870 μm of 1.85 cm²g⁻¹, and a dust absorption coefficient β of 1.8. The yellow and green bands indicate the uncertainty in the modelled fluxes for the 68 and 95% credibility intervals of T_dust and M_dust, assuming that the uncertainty on the measured fluxes is 20%.
