Abstract:
We describe data release 3 (DR3) of the Galaxy And Mass Assembly
(GAMA) survey. The GAMA survey is a spectroscopic redshift and
multiwavelength photometric survey in three equatorial regions each of
60.0deg2 (G09, G12, and G15), and two southern regions of
55.7deg2 (G02) and 50.6deg2 (G23). DR3 consists of: the first
release of data covering the G02 region and of data on H-ATLAS
(Herschel - Astrophysical Terahertz Large Area Survey) sources in
the equatorial regions; and updates to data on sources released in
DR2. DR3 includes 154809 sources with secure redshifts across four
regions. A subset of the G02 region is 95.5 per cent redshift
complete to r<19.8mag over an area of 19.5deg2, with 20086
galaxy redshifts, that overlaps substantially with the XXL survey
(X-ray) and VIPERS (redshift survey). In the equatorial regions, the
main survey has even higher completeness (98.5 per cent), and
spectra for about 75 per cent of H-ATLAS filler targets were also
obtained. This filler sample extends spectroscopic redshifts, for
probable optical counterparts to H-ATLAS submillimetre sources, to
0.8mag deeper (r<20.6mag) than the GAMA main survey. There are
25814 galaxy redshifts for H-ATLAS sources from the GAMA main or
filler surveys. GAMA DR3 is available at the survey website
(www.gama-survey.org/dr3/).
Description:
The third GAMA data release (DR3) provides AAT/AAOmega spectra,
redshifts, and a wealth of ancillary information for primarily 215260
objects from the GAMA II survey (Table 1). Of these, 178856 are
main-survey objects and 36404 are fillers. In turn, 150465
(84 per cent) and 4344 (12 per cent) of these, respectively,
have secure redshifts. DR3 updates all data previously released in
DR2, and significantly expands on DR2: DR3 includes both more objects
and a wider range of data products than DR2. DR3 thus supersedes DR2
in every way. The DR is available at: http://www.gama-survey.org/dr3/.
