We present the broad-band UV through mid-infrared spectral energy distributions (SEDs) of a sample of 72 spectroscopically-confirmed star-forming galaxies at z = 2.30± 0.3. Located in a 72 arcmin field centered on the bright background QSO, HS1700+643, these galaxies were pre-selected to lie at z ∼ 2 based solely on their rest-frame UV colors and luminosities, and should be representative of UV...
