CANDELS/GOODS-S, CDFS, ECDFS: Photometric Redshifts For Normal and for
  X-Ray-Detected Galaxies
  We present photometric redshifts and associated probability distributions for
all detected sources in the Extended Chandra Deep Field South (ECDFS). The work
makes use of the most up-to-date data from the Cosmic Assembly Near-IR Deep
Legacy Survey (CANDELS) and the Taiwan ECDFS Near-Infrared Survey (TENIS) in
addition to other data. We also revisit multi-wavelength counterparts for
published X-ray sources from the 4Ms-CDFS and 250ks-ECDFS surveys, finding
reliable counterparts for 1207 out of 1259 sources ($\sim 96\%$). Data used for
photometric redshifts include intermediate-band photometry deblended using the
TFIT method, which is used for the first time in this work. Photometric
redshifts for X-ray source counterparts are based on a new library of
AGN/galaxy hybrid templates appropriate for the faint X-ray population in the
CDFS. Photometric redshift accuracy for normal galaxies is 0.010 and for X-ray
sources is 0.014, and outlier fractions are $4\%$ and $5.4\%$ respectively. The
results within the CANDELS coverage area are even better as demonstrated both
by spectroscopic comparison and by galaxy-pair statistics. Intermediate-band
photometry, even if shallow, is valuable when combined with deep broad-band
photometry. For best accuracy, templates must include emission lines.
