| 英文摘要 | We present deep J- and H-band images in the extended Great Observatories Origins Deep Survey-North field covering an area of 0.22 deg(2). The observations were taken using WIRCam on the 3.6 m Canada-France-Hawaii Telescope. Together with the reprocessed K-s-band image, the 5 sigma limiting AB magnitudes (in 2 '' diameter apertures) are 24.7, 24.2, and 24.4 AB. mag in the J, H, and K-s bands, respectively. We also release a multiband photometry and photometric redshift catalog containing 93,598 sources. For non-X-ray sources, we obtained a photometric redshift accuracy sigma(NMAD) = 0.036 with an outlier fraction eta = 7.3%. For X-ray sources, which are mainly active galactic nuclei (AGNs), we cross-matched our catalog with the updated 2M-CDFN X-ray catalog from Xue et al. and found that 658 out of 683 X-ray sources have counterparts. GALEX UV data are included in the photometric redshift computation for the X-ray sources to give sigma(NMAD) = 0.040 with eta = 10.5%. Our approach yields more accurate photometric redshift estimates compared to previous works in this field. In particular, by adopting AGN-galaxy hybrid templates, our approach delivers photometric redshifts for the X-ray counterparts with fewer outliers compared to the 3D-Hubble Space Telescope catalog, which fit these sources with galaxy-only templates. |
