Abstract

We derive z phot for sources in the entire (∼0.4 deg²) H-HDF-N field with the EAzY code, based on PSF-matched broad-band (U band to IRAC 4.5 μm) photometry. Our catalog consists of a total of 131,678 sources. We find σNMAD = 0.029 for non-X-ray sources. We also classify each object as a star or galaxy through SED fitting. Furthermore, we match our catalog with the 2 Ms CDF-N main X-ray catalog. For the 462 matched non-stellar X-ray sources, we improve their z phot quality (σNMAD = 0.035) by adding three additional AGN templates. We make our photometry and z phot catalog publicly available.
