26 Jun 2015 | | Abstract: | The Galaxy And Mass Assembly (GAMA) survey is one of the largest contemporary
spectroscopic surveys of low-redshift galaxies. Covering an area of ~286 deg^2
(split among five survey regions) down to a limiting magnitude of r < 19.8 mag,
we have collected spectra and reliable redshifts for 238,000 objects using the
AAOmega spectrograph on the Anglo-Australian Telescope. In addition, we have
assembled imaging data from a number of independent surveys in order to
generate photometry spanning the wavelength range 1 nm - 1 m. Here we report on
the recently completed spectroscopic survey and present a series of diagnostics
to assess its final state and the quality of the redshift data. We also
describe a number of survey aspects and procedures, or updates thereof,
including changes to the input catalogue, redshifting and re-redshifting, and
the derivation of ultraviolet, optical and near-infrared photometry. Finally,
we present the second public release of GAMA data. In this release we provide
input catalogue and targeting information, spectra, redshifts, ultraviolet,
optical and near-infrared photometry, single-component S’ersic fits, stellar
masses, H$alpha$-derived star formation rates, environment information, and
group properties for all galaxies with r < 19.0 mag in two of our survey
regions, and for all galaxies with r < 19.4 mag in a third region (72,225
objects in total). The database serving these data is available at
