Ldust/1020 [W] | 2.84 ± 0.14 | 2.43 ± 0.12 | 2.57 ± 0.13 |
Notes. PL+G_MBB is based on a power law in the mid-IR plus the general blackbody formula as in Casey (2012); PL+OT_MBB is a power law in the mid-IR (αMIR) plus an optically thin blackbody, which is again similar to Casey (2012); and DL2014 stands for Draine et al. (2014) models. The parameters are described in Appendix A. Because the SEDs were normalized to 1.0 at λ = 200 μm, the values of Ldust can be directly compared.
