We release homogeneously computed photo-z and associated P(z) for both galaxies and X-ray detected AGNs (105150 sources in total) in the area covered by CANDELS/GOODS-S, CDFS and ECDFS survey. Making the use of the most up-to-date data from the Cosmic Assembly Near-IR Deep Legacy Survey (CANDELS; Guo et al. 2013) and the Taiwan ECDFS Near-Infrared Survey (TENIS; Hsieh et al. 2012) in addition to the ancillary data (e.g., GALEX and MUSYC photometry), we compute photo-z with the photometry from UV to MIR for a total of 50 filters. We achieve a photo-z accuracy of σ=0.010 with an outlier fraction of 4% for galaxies, and σ =0.014 with an outlier fraction of 5.4% for the X-ray detected AGNs.
In addition to the photo-z results, we also provide a compilation of all the X-ray sources from the literature 4Ms-CDFS ( Rangel et al. 2013; Xue et al. 2011) and 250ks-ECDFS (Lehmer et al. 2005; Virani et al. 2006) along with the new optical/NIR/IR associations. Using the Bayesian method (Salvato et al., in prep), we found for 1207 out of 1259 (96%) a reliable counterpart.
The detailed descriptions and discussion for these results are presented in Hsu et al., 2014. Here we provide:
Area coverage in J + Ks image from the TENIS Survey. The outer dashed line (ECDFS) covers the areas of CDFS (black solid line) and CANDELS/GOODS-S (inner dashed line) regions. Area 1 refers to the CANDELS field, Area 2 and Area 3 refer to the areas of (CDFS − CANDELS) and (ECDFS − CDFS), respectively.
X-ray data for the CDFS-4Ms and the Extended-CDFS survey fields. These include event files, X-ray images,
exposure and background maps in differenet energy band for both the individual Chandra observations in the fields above
and the merged products. For the latter we also provide sensitivity maps and sensitivity curves in
different energy bands. The CDFS-4Ms X-ray catalogue is presented in Rangel et al. (2013). The Extended-CDFS data reduction and source detection is described in Georgakakis et al. (2008).
Please cite those paper if you find these data products useful. The tarballs include README files with
information about the released data products. X-ray source catalogues including extensive X-ray information on individual sources are also provided for CDFS-4Ms and for ECDFS.
Spectroscopic and/or photometric redshifts for the optical/NIR candidate counterparts to an X-ray detection. A link to the SED fitting and entire P(z) for each of the candidates counterparts is also provided in the last column of the table.
AB magnitude and associated photometric error in each broad- and intermediate-filter bands used for computing the photometric redshifts for the sources associated with the X-ray detection. We report here the photometry for all the possible sources associated to an X-ray detection (i.e. for the same XID, more than one row of photometric values are listed).
A useful Cross-ID table to navigate through all the X-ray and Optical/NIR/MIR catalogs used for Hsu et al. 2014 paper.
In Brightman et al. (2014), an X-ray spectral analysis was carried out on the sources from the 4Ms Chandra data using the redshifts described on this page. This analysis determined the absorption (NH) and intrinsic X-ray luminosity of each source, the results of which are available here.
