The CANDELS/SHARDS Multiwavelength Catalog in GOODS-N: Photometry, Photometric Redshifts, Stellar Masses, Emission-line Fluxes, and Star Formation Rates

Abstract

We present a WFC3 F160W ($H$-band) selected catalog in the CANDELS/GOODS-N\nfield containing photometry from the ultraviolet (UV) to the far-infrared (IR),\nphotometric redshifts and stellar parameters derived from the analysis of the\nmulti-wavelength data. The catalog contains 35,445 sources over the 171\narcmin$^{2}$ of the CANDELS F160W mosaic. The 5$\\sigma$ detection limits\n(within an aperture of radius 0\\farcs17) of the mosaic range between $H=27.8$,\n28.2 and 28.7 in the wide, intermediate and deep regions, that span\napproximately 50\\%, 15\\% and 35\\% of the total area. The multi-wavelength\nphotometry includes broad-band data from UV (U band from KPNO and LBC), optical\n(HST/ACS F435W, F606W, F775W, F814W, and F850LP), near-to-mid IR (HST/WFC3\nF105W, F125W, F140W and F160W, Subaru/MOIRCS Ks, CFHT/Megacam K, and\n\\spitzer/IRAC 3.6, 4.5, 5.8, 8.0 $\\mu$m) and far IR (\\spitzer/MIPS 24$\\mu$m,\nHERSCHEL/PACS 100 and 160$\\mu$m, SPIRE 250, 350 and 500$\\mu$m) observations. In\naddition, the catalog also includes optical medium-band data (R$\\sim50$) in 25\nconsecutive bands, $\\lambda=500$ to 950~nm, from the SHARDS survey and WFC3 IR\nspectroscopic observations with the G102 and G141 grisms (R$\\sim210$ and 130).\nThe use of higher spectral resolution data to estimate photometric redshifts\nprovides very high, and nearly uniform, precision from $z=0-2.5$. The\ncomparison to 1,485 good quality spectroscopic redshifts up to $z\\sim3$ yields\n$\\Delta z$/(1+$z_{\\rm spec}$)$=$0.0032 and an outlier fraction of $\\eta=$4.3\\%.\nIn addition to the multi-band photometry, we release added-value catalogs with\nemission line fluxes, stellar masses, dust attenuations, UV- and IR- based star\nformation rates and rest-frame colors.\n
