Abstract:
The Galaxy and Mass Assembly (GAMA) survey has been operating since
2008 February on the 3.9-m Anglo-Australian Telescope using the
AAOmega fibre-fed spectrograph facility to acquire spectra with a
resolution of R 1300 for 120862 Sloan Digital Sky Survey selected
galaxies. The target catalogue constitutes three contiguous equatorial
regions centred at 9h (G09), 12h (G12) and 14.5h (G15) each of
12x4deg^2^ to limiting fluxes of r_pet_<19.4, r_pet_<19.8 and
r_pet_<19.4 mag, respectively (and additional limits at other
wavelengths). Spectra and reliable redshifts have been acquired for
over 98 per cent of the galaxies within these limits. Here we present
the survey footprint, progression, data reduction, redshifting,
re-redshifting, an assessment of data quality after 3yr, additional
image analysis products (including ugrizYJHK photometry, Sersic
profiles and photometric redshifts), observing mask and construction
of our core survey catalogue (GamaCore). From this we create three
science-ready catalogues: GamaCoreDR1 for public release, which
includes data acquired during year 1 of operations within specified
magnitude limits (2008 February to April); GamaCoreMainSurvey
containing all data above our survey limits for use by the GAMA Team
and collaborators; and GamaCoreAtlasSV containing year 1, 2 and 3 data
matched to Herschel-ATLAS science demonstration data. These catalogues
along with the associated spectra, stamps and profiles can be accessed
via the GAMA website: http://www.gama-survey.org/
Description:
All GAMA 2dF pointings (tiles) were observed during dark or grey time
with exposure times mostly ranging from 3000 to 5000s (in three to
five exposures) depending on seeing and sky brightness. Observations
were generally conducted at an hour angle of less than 2h (the median
zenith distance of the observations is 35deg) and with the
Atmospheric Dispersion Corrector engaged. We used the 580V and 385R
gratings with central wavelengths of 4800 and 7250AA in the blue
and red arms, respectively, separated by a 5700AA dichroic. This
set-up yielded a continuous wavelength coverage of 3720-8850AA at a
resolution of 3.5AA (in the blue channel) and 5.5AA (in the red
channel).
