The SAMI Galaxy Survey: Data Release One with Emission-line Physics
  Value-Added Products
  We present the first major release of data from the SAMI Galaxy Survey. This
data release focuses on the emission-line physics of galaxies. Data Release One
includes data for 772 galaxies, about 20% of the full survey. Galaxies included
have the redshift range 0.004 < z < 0.092, a large mass range (7.6 <
log(Mstellar/M$_\odot$) < 11.6), and star-formation rates of 10^-4 to 10^1\
M$_\odot$/yr. For each galaxy, we include two spectral cubes and a set of
spatially resolved 2D maps: single- and multi-component emission-line fits
(with dust extinction corrections for strong lines), local dust extinction and
star-formation rate. Calibration of the fibre throughputs, fluxes and
differential-atmospheric-refraction has been improved over the Early Data
Release. The data have average spatial resolution of 2.16 arcsec (FWHM) over
the 15~arcsec diameter field of view and spectral (kinematic) resolution R=4263
(sigma=30km/s) around Halpha. The relative flux calibration is better than 5\%
and absolute flux calibration better than $\pm0.22$~mag, with the latter
estimate limited by galaxy photometry. The data are presented online through
the Australian Astronomical Observatory's Data Central.
