Rayleigh Scattering is a physical effect that is not typically included in standard LTE abundance analysis programs like MOOG.  However, Rayleigh scattering has been shown to be important for metal-poor stars, particularly in the blue spectral regions.  In this poster, we investigate the effects of Rayleigh Scattering on abundances derived from Integrated Light (IL) spectra, using the new version of MOOG-SCAT developed by Jennifer Sobeck.
