(Left) Dust temperatures inferred from the combination of PACS only (or SPIRE only) together with submm observations, compared with the reference values inferred using PACS, SPIRE and submm observations. These comparisons are for our power-law temperature distribution model. Symbols are the same as in Fig. 2. (Right) Same comparison but for the inferred infrared luminosities. The dust temperatures and infrared luminosities of galaxies can be reasonably inferred from their PACS+submm or their SPIRE+submm observations alone using a temperature distribution model.
