The Temperature-Luminosity plane showing a variety of FIR populations. Open squares are SMGs from Chapman et al. (2005), open triangles are SMGs observed with SHARCII by Coppin et al. (2008) and Kovács et al. (2006). + signs are the SLUGS sources from Dunne et al. (2000),  ×  are intermediate redshift ULIRGs from Yang et al. (2007), ULIRGs from Clements et al. (2010b) are open circles. Planck-ERCSC-IIFSCz galaxies are shown as solid dots. As can be seen the previous apparent distinction between the local FIR populations and the SMGs is weakened by sources from this work lying in the same region as the SMGs and by filling in some of the gap between the populations. The four aberrant sources with T < 15 K and high L in the bottom right of the plot are the non-thermal dominated sources 3C279, 0537-441, OJ+287 and 3C273.
