摘要

The Spitzer Extended Deep Survey(SEDS)as a deep and wide mid-infrared(MIR)survey project provides a sample of 500 000+sources spreading 1.46 square degree and a depth of 26 AB mag(3σ).Combining with the previous available data,we build a PSF-matched multi-wavelength photometry catalog from u band to 8 μm.We fit the SEDS galaxies spectral energy distributions by the local galaxy templates.The results show that the SEDS galaxy can be fitted well,indicating the high redshift galaxy(z～1)shares the same templates with the local galaxies.This study would facilitate the further study of the galaxy luminosity and high redshift mass function.
