abstract = "In this paper we present a thorough discussion about the
photometric redshift (photo-z) performance of the Southern
Photometric Local Universe Survey (S-PLUS). This survey combines a
seven narrow +5 broad passband filter system, with a typical
photometric-depth of r similar to 21 AB. For this exercise, we
utilize the Data Release 1 (DR1), corresponding to 336 deg(2) from
the Stripe-82 region. We rely on the BPZ2 code to compute our
estimates, using a new library of SED models, which includes
additional templates for quiescent galaxies. When compared to a
spectroscopic redshift control sample of similar to 100 k
galaxies, we find a precision of o z sigma(z)<0.8 per cent, <2.0
per cent, or <3.0 per cent for galaxies with magnitudes r < 17,
<19, and <21, respectively. A precision of 0.6 per cent is
attained for galaxies with the highest Odds values. These
estimates have a negligible bias and a fraction of catastrophic
outliers inferior to 1 percent. We identify a redshift window
(i.e. 0.26 < z < 0.32) where our estimates double their precision,
due to the simultaneous detection of two emission lines in two
distinct narrow bands; representing a window opportunity to
conduct statistical studies such as luminosity functions. We
forecast a total of similar to 2 M, similar to 16 M and similar to
32 M galaxies in the S-PLUS survey with a photo-z precision of
sigma(z) <1.0 per cent, <2.0 per cent, and <2.5 per cent after
observing 8000 deg(2). We also derive redshift probability density
functions, proving their reliability encoding redshift
uncertainties and their potential recovering the n(z) of galaxies
at z < 0.4, with an unprecedented precision for a photometric
survey in the Southern hemisphere.",
