我们提出了SAMI星系调查数据的第一个主要版本。本数据发布的重点是星系的发射线物理学。数据发布一包括772个星系的数据，约占全部调查的20%。星系的红移范围为0.004 < z < 0.092，质量范围很大（7.6 < log M*/ M < 11.6），星星的形成速率为1010 ^（−4）到1010 ^1 M yr^（−1）。对于每个星系，我们包括两个光谱立方体和一组空间分辨的二维地图：单和多分量发射线拟合（强线的尘埃消光校正），本地尘埃消光，和星星形成率。光纤吞吐量、通量和差分大气折射的校准在早期数据发布中得到了改进。这些数据在15弧秒直径的视场内的平均空间分辨率为2.16弧秒（半高全宽），在H α周围的光谱（运动学）分辨率为R = 4263（σ = 30 km s^（-1））。相对通量校准优于5%，绝对通量校准的均方根值为10%，数据通过澳大利亚天文台的数据中心在线提供。
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 per cent of the full survey. Galaxies included have the redshift range 0.004 < z < 0.092, a large mass range (7.6 < log M*/ M⊙ < 11.6), and star formation rates of ∼10^(−4) to ∼10^1M⊙ yr^(−1). 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 (full width at half-maximum) over the 15 arcsec diameter field of view and spectral (kinematic) resolution of R = 4263 (σ = 30 km s^(−1)) around H α. The relative flux calibration is better than 5 per cent, and absolute flux calibration has an rms of 10 per cent. The data are presented online through the Australian Astronomical Observatory's Data Central.
