S-PLUS Cloud

The Southern Photometric Local Universe Survey (S-PLUS) is imaging ˜9300 deg2 of the celestial sphere in 12 optical bands (see the Figure above) 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 (μ m) 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 higher than 19.7 AB mag and z lower than 0.4, thus producing a 3D map of the local Universe over a volume of more than 1 (Gpc/h)^3. S-PLUS data will enable, among other studies, investigating new asteroids of the Solar System, studying the star formation rates and stellar populations in and around the Milky Way and nearby galaxies, as well as searches for quasars, variable sources, and low-metallicity stars. DR1 was released in March 2019, together with the first paper of the collaboration Mendes de Oliveira et al. (2019).
