We show that measures of star formation rates (SFRs) for infrared galaxies using either single-band 24 μm or extinction-corrected Paα luminosities are consistent in the total infrared luminosity = L(TIR) ∼ 1010 L☉ range. MIPS 24 μm photometry can yield SFRs accurately from this luminosity upward: SFR(M☉ yr−1) = 7.8 × 10−10 L(24 μm, L☉) from L(TIR) = 5× 109 L☉ to 1011 L☉ and SFR = 7.8 × 10−10 L(24 μm, L☉)(7.76 × 10−11L(24))0.048 for higher L(TIR). For galaxies with L(TIR) ⩾ 1010 L☉, these new expressions should provide SFRs to within 0.2 dex. For L(TIR) ⩾ 1011 L☉, we find that the SFR of infrared galaxies is significantly underestimated using extinction-corrected Paα (and presumably using any other optical or near-infrared recombination lines). As a part of this work, we constructed spectral energy distribution templates for eleven luminous and ultraluminous purely star forming infrared galaxies and over the spectral range 0.4 μm to 30 cm. We use these templates and the SINGS data to construct average templates from 5 μm to 30 cm for infrared galaxies with L(TIR) = 5× 109 to 1013 L☉. All of these templates are made available online.

GOODS-HERSCHEL MEASUREMENTS OF THE DUST ATTENUATION OF TYPICAL STAR-FORMING GALAXIES AT HIGH REDSHIFT: OBSERVATIONS OF ULTRAVIOLET-SELECTED GALAXIES AT z ∼ 2 (2011, methodology): “To interprete these fluxes, we consider a variety of dust templates, including those of Elbaz et al. (2011), Chary & Elbaz (2001), Dale & Helou (2002), and Rieke et al. (2009), as well as the 24µm-LIR and radioinfrared correlations of Reddy et al. (2010) and Bell (2003), respectively.”
Physical properties and environments of nearby galaxies (2009, methodology): “…observations with Spitzer and GALEX have led to a new class of hybrid SFR indicators that use a weighted combination of UV/optical and infrared luminosity to minimize the systematic effects of dust obscuration (Gordon et al. 2000; Kennicutt et al. 2007; Calzetti et al. 2007; Rieke et al. 2008.”

A TURNOVER IN THE GALAXY MAIN SEQUENCE OF STAR FORMATION AT M* ∼ 1010 M☉ FOR REDSHIFTS z < 1.3 (2015, methodology): “A common method of determining the LIR of less luminous galaxies is to use deep Spitzer 24 µm data to estimate the far-infrared luminosity (e.g. Kennicutt et al. 2009; Rieke et al. 2009; Rujopakarn et al. 2013).”
OPTICAL SPECTROSCOPY AND NEBULAR OXYGEN ABUNDANCES OF THE SPITZER/SINGS GALAXIES (2010, methodology): “First, the calibrated emission-line spectra provide measures of the instantaneous SFR and dust reddening that can be compared to independent measures of SFRs and extinctions derived from 233 the UV and IR (e.g., Kennicutt et al. 2009; Calzetti et al. 2007, 2010; Rieke et al. 2009).”

IDENTIFYING LUMINOUS ACTIVE GALACTIC NUCLEI IN DEEP SURVEYS: REVISED IRAC SELECTION CRITERIA (2012, background): “To better isolate the sources most likely to be starforming contaminants, we develop the following empirical criteria to identify high-z sources whose IRAC photometry can plausibly be fit by the Rieke et al.
