Abstract:
The Southern Photometric Local Universe Survey (S-PLUS) is a project
to map ∼9300 sq deg of the sky using twelve bands (seven narrow and
five broadbands). Observations are performed with the T80-South
telescope, a robotic telescope located at the Cerro Tololo Observatory
in Chile. The survey footprint consists of several large contiguous
areas, including fields at high and low galactic latitudes, and
towards the Magellanic Clouds. S-PLUS uses fixed exposure times to
reach point source depths of about 21mag in the griz and 20mag
in the u and the narrow filters.
This paper describes the S-PLUS Data Release 4 (DR4), which includes
calibrated images and derived catalogues for over 3000 sq deg,
covering the aforementioned area. The catalogues provide multi-band
photometry performed with the tools DoPHOT and SExtractor - point
spread function (PSF) and aperture photometry, respectively. In
addition to the characterization, we also present the scientific
potential of the data.
We use statistical tools to present and compare the photometry
obtained through different methods. Overall we find good agreement
between the different methods, with a slight systematic offset of
0.05mag between our PSF and aperture photometry. We show that the
astrometry accuracy is equivalent to that obtained in previous S-PLUS
data releases, even in very crowded fields where photometric
extraction is challenging. The depths of main survey (MS) photometry
for a minimum signal-to-noise ratio S/N=3 reach from ∼19.5 for the
bluer bands to ∼21.5mag on the red. The range of magnitudes over which
accurate PSF photometry is obtained is shallower, reaching ∼19 to
∼20.5mag depending on the filter. Based on these photometric data, we
provide star-galaxy-quasar classification and photometric redshift for
millions of objects.
We demonstrate the versatility of the data by presenting the results
of a project to identify members of four Abell galaxy clusters in the
Local Universe. The S-PLUS DR4 data allow for a reliable assessment of
cluster membership out to a large radius corresponding to 5*r200.
The S-PLUS DR4 can be accessed through the survey data portal. All the
software used to generate the catalogues for this release and the
scientific investigation presented is available in the collaboration
GitHub repository.
The S-PLUS DR4 consists of a large, calibrated public dataset,
providing powerful ways for studying Galactic and extra-galactic
objects through an extensive set of (broad and narrow) filters.
Description:
This is the data release 4 (DR4), open to S-PLUS members only. It
includes 1629 fields, covering about 3000 square degrees of the
southern sky. It contains the same regions from the previous DRs (1, 2
and 3) as well as new data from the Magellanic clouds, the disk of the
Galaxy and some additional high galactic latitude fields. The data
reduction is still done the same way but the photometry and the
calibration (for all the data in DR4) were done slightly differently,
using the most recent version of the pipelines (as described below).
Besides the SExtractor photometry, PSF photometry is also performed -
this is very important in the crowded fields of the Magellanic clouds
and of the disk of our Galaxy. It is important to note that a few of
the columns used in DR3 now have different identifications in DR4 (see
list of column names). Another important point to note is that the
queries have changed (because the tables structure changed in
important ways).
The photometric catalog corresponds to the description in table C4
(catalogues for the PSF-mode photometry) of the paper.
