 * Formulas for Star Formation Rates

Luminosity formula¹** LTIR(galaxy) = c x L15(galaxy) c= Ratio of the integral of the SED curve and luminosity at rest-frame wavelength L15(galaxy)=observed luminosity at a specific wavelength

c=(∫SED dλ)/ λrest ∫SED dλ=Area under the SED curve as a function of wavelength with limits of 8 microns to 1000 microns λrest=luminosity at rest-frame wavelength

λrest=λobserved/(1+z) z=redshift value λobserved=luminosity at an observed wavelength

SFR ( /yr) = 4.5 x 10-44 x LTIR (ergs/s)
 * Star Formation Rate formula¹**

SFR= Star Formation Rate in Solar Masses per year (/yr) LTIR= total infrared luminosity in ergs per second (ergs/s)
