                         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.",
