Here you can find a short IDL code to compute the dust temperature of a galaxy from its redshift, SFR and stellar mass. These estimates are based on the results of Magnelli et al. (2013; Eq. 5). If asked, this IDL code will also predict the observed monochromatic fluxes of the galaxy, based on Dale & Helou (2002) SED templates.
More details about the code and about the adopted quantities can be found in the associated README file and in the IDL source itself.
