Mid-Infrared Star Formation Indicators (MIR_SFR)

Continuous, monochromatic star formation rate (SFR) indicators over the mid-infrared wavelength range of 6 - 70 microns are available below. These indicators were derived from a sample of 58 star forming galaxies (SFGs) in the Spitzer-SDSS-GALEX Spectroscopic Survey (SSGSS) at z < 0.2, for which there is a rich suite of multi-wavelength photometry and spectroscopy from the ultraviolet through to the infrared. The data from the Spitzer infrared spectrograph (IRS) of these galaxies, which spans 5 - 40 microns, is anchored to their photometric counterparts. The spectral region between 40 - 70 microns is interpolated using dust model fits to the IRS spectrum and Spitzer 70 and 160 micron photometry.
