| Abstract: | We present a WFC3 F160W ($H$-band) selected catalog in the CANDELS/GOODS-N
field containing photometry from the ultraviolet (UV) to the far-infrared (IR),
photometric redshifts and stellar parameters derived from the analysis of the
multi-wavelength data. The catalog contains 35,445 sources over the 171
arcmin$^{2}$ of the CANDELS F160W mosaic. The 5$sigma$ detection limits
(within an aperture of radius 0farcs17) of the mosaic range between $H=27.8$,
28.2 and 28.7 in the wide, intermediate and deep regions, that span
approximately 50\%, 15\% and 35\% of the total area. The multi-wavelength
photometry includes broad-band data from UV (U band from KPNO and LBC), optical
(HST/ACS F435W, F606W, F775W, F814W, and F850LP), near-to-mid IR (HST/WFC3
F105W, F125W, F140W and F160W, Subaru/MOIRCS Ks, CFHT/Megacam K, and
spitzer/IRAC 3.6, 4.5, 5.8, 8.0 $mu$m) and far IR (spitzer/MIPS 24$mu$m,
HERSCHEL/PACS 100 and 160$mu$m, SPIRE 250, 350 and 500$mu$m) observations. In
addition, the catalog also includes optical medium-band data (R$sim50$) in 25
consecutive bands, $lambda=500$ to 950~nm, from the SHARDS survey and WFC3 IR
spectroscopic observations with the G102 and G141 grisms (R$sim210$ and 130).
The use of higher spectral resolution data to estimate photometric redshifts
provides very high, and nearly uniform, precision from $z=0-2.5$. The
comparison to 1,485 good quality spectroscopic redshifts up to $zsim3$ yields
$Delta z$/(1+$z_{
m spec}$)$=$0.0032 and an outlier fraction of $eta=$4.3\%.
In addition to the multi-band photometry, we release added-value catalogs with
emission line fluxes, stellar masses, dust attenuations, UV- and IR- based star
formation rates and rest-frame colors. |
