Abstract:
The WiggleZ Dark Energy Survey is a survey of 240000 emission-line
galaxies in the distant Universe, measured with the AAOmega
spectrograph on the 3.9-m Anglo-Australian Telescope (AAT). The
primary aim of the survey is to precisely measure the scale of baryon
acoustic oscillations (BAO) imprinted on the spatial distribution of
these galaxies at look-back times of 4-8Gyr.
The target galaxies are selected using ultraviolet (UV) photometry
from the Galaxy Evolution Explorer satellite, with a flux limit of
NUV<22.8mag. We also require that the targets are detected at optical
wavelengths, specifically in the range 20.0<r<22.5mag. We use the
Lyman break method applied to the UV colours, with additional optical
colour limits, to select high-redshift galaxies. The galaxies
generally have strong emission lines, permitting reliable redshift
measurements in relatively short exposure times on the AAT. The median
redshift of the galaxies is zmed=0.6. The redshift range containing
90 per cent of the galaxies is 0.2<z<1.0.
The survey will sample a volume of ∼1Gpc3 over a projected area on
the sky of 1000deg2, with an average target density of 350deg-2.

Note (1): Redshift Quality Definitions:
1 = No redshift was possible; highly noisy spectra.
2 = An uncertain redshift was assigned.
3 = A reasonably confident redshift; if based on [OII] alone,
then the doublet is resolved or partially resolved.
4 = A redshift that has multiple (obvious) emission lines all in agreement.
5 = An excellent redshift with high S/N that may be suitable as a template.
6 = Reserved for Galactic stars used as calibration sources.
Note (2): SDSS-DR4 data (Cat. II/267) for the North Galactic Pole, and
RCS2 (Red-sequence Cluster Survey, a project of the Canada-France-Hawaii
Telescope [CFHT]) for the South Galactic Pole.
Note (3): "ANN" represent the regions, where "NN" represents the hour
of right ascension: 00, 01, 03 and 22 for the South Galactic Pole;
09, 11 and 15 for the North Galactic Pole.
