Resumo
The Southern Photometric Local Universe Survey (S-PLUS) is imaging ∼9300 deg2 of the
celestial sphere in 12 optical bands using a dedicated 0.8 m robotic telescope, the T80-South, at
the Cerro Tololo Inter-american Observatory, Chile. The telescope is equipped with a 9.2k ×
9.2k e2v detector with 10 μm pixels, resulting in a field of view of 2 deg2 with a plate
scale of 0.55 arcsec pixel−1. The survey consists of four main subfields, which include two
non-contiguous fields at high Galactic latitudes (|b| > 30◦
, 8000 deg2) and two areas of the
Galactic Disc and Bulge (for an additional 1300 deg2). S-PLUS uses the Javalambre 12-band
magnitude system, which includes the 5 ugriz broad-band filters and 7 narrow-band filters
centred on prominent stellar spectral features: the Balmer jump/[OII], Ca H + K, H δ, G band,
Mg b triplet, H α, and the Ca triplet. S-PLUS delivers accurate photometric redshifts (δz/(1 +
z) = 0.02 or better) for galaxies with r < 19.7 AB mag and z < 0.4, thus producing a 3D map
of the local Universe over a volume of more than 1 (Gpc/h)
3. The final S-PLUS catalogue
will also enable the study of star formation and stellar populations in and around the Milky
Way and nearby galaxies, as well as searches for quasars, variable sources, and low-metallicity
stars. In this paper we introduce the main characteristics of the survey, illustrated with science
verification data highlighting the unique capabilities of S-PLUS. We also present the first
public data release of ∼336 deg2 of the Stripe 82 area, in 12 bands, to a limiting magnitude of
r = 21, available at datalab.noao.edu/splus.
