Abstract

We derive photometric redshifts (Z(phot)) for sources in the entire (similar to 0.4 deg(2)) Hawaii-Hubble Deep Field-North (H-HDF-N) field with the EAzY code, based on point-spread-function-matched photometry of 15 broad bands from the ultraviolet (U band) to mid-infrared (IRAC 4.5 mu m). Our catalog consists of a total of 131,678 sources. We evaluate the Z(phot) quality by comparing Z(phot) with spectroscopic redshifts (Z(spec)) when available, and find a value of normalized median absolute deviation sigma(NMAD) = 0.029 and an outlier fraction of 5.5% (outliers are defined as sources having vertical bar Z(phot) - Z(spec)vertical bar/(1 + Z(spec)) > 0.15) for non-X-ray sources. More specifically, we obtain sigma(NMAD) = 0.024 with 2.7% outliers for sources brighter than R = 23 mag, sigma(NMAD) = 0.035 with 7.4% outliers for sources fainter than R = 23 mag, sigma(NMAD) = 0.026 with 3.9% outliers for sources having z < 1, and sigma(NMAD) = 0.034 with 9.0% outliers for sources having z > 1. Our Z(phot) quality shows an overall improvement over an earlier Z(phot) work that focused only on the central H-HDF-N area. We also classify each object as a star or galaxy through template spectral energy distribution fitting and complementary morphological parameterization, resulting in 4959 stars and 126,719 galaxies. Furthermore, we match our catalog with the 2 Ms Chandra Deep Field-North main X-ray catalog. For the 462 matched non-stellar X-ray sources (281 having Z(spec)), we improve their Z(phot) quality by adding three additional active galactic nucleus templates, achieving sigma(NMAD) = 0.035 and an outlier fraction of 12.5%. We make our catalog publicly available presenting both photometry and Z(phot), and provide guidance on how to make use of our catalog.
