Abstract:
We present the Early Data Release of the Sydney-AAO Multi-object
Integral field spectrograph (SAMI) Galaxy Survey. The SAMI Galaxy
Survey is an ongoing integral field spectroscopic survey of ∼3400
low-redshift (z<0.12) galaxies, covering galaxies in the field
and in groups within the Galaxy And Mass Assembly (GAMA) survey
regions, and a sample of galaxies in clusters. In the Early Data
Release, we publicly release the fully calibrated data cubes for a
representative selection of 107 galaxies drawn from the GAMA regions,
along with information about these galaxies from the GAMA catalogues.
All data cubes for the Early Data Release galaxies can be downloaded
individually or as a set from the SAMI Galaxy Survey website. In this
paper we also assess the quality of the pipeline used to reduce the
SAMI data, giving metrics that quantify its performance at all stages
in processing the raw data into calibrated data cubes. The pipeline
gives excellent results throughout, with typical sky subtraction
residuals in the continuum of 0.9-1.2 per cent, a relative flux
calibration uncertainty of 4.1 per cent (systematic) plus 4.3 per cent
(statistical), and atmospheric dispersion removed with an accuracy of
0.09-arcsec, less than a fifth of a spaxel.
Description:
The targets for the SAMI Galaxy Survey are drawn from the GAMA survey
G09, G12 and G15 fields, as well as a set of eight galaxy clusters
that extend the survey to higher environmental densities. All
candidates have known redshifts from GAMA, SDSS or dedicated 2dF
observations, allowing us to create a tiered set of volume-limited
samples. Full details of the target selection are presented in Bryant
et al. (2015MNRAS.447.2857B 2015MNRAS.447.2857B).
The 107 galaxies that form the SAMI Galaxy Survey EDR are those
contained in nine fields in the GAMA regions that were observed in
2013 March and April.
