论文摘要
我们介绍并公开提供了凯克天文台数据库的第三个数据释放（DR3），该数据库是针对类星体（KODIAQ）调查的。 Kodiaq DR3由0.1 <z <6.4的727种类星体的样品组成，在中度分辨率下使用ESI观察到（4000 <r <10000）。 DR3包含872个光谱以通量校准形式可用，代表总计总暴露时间约为2.8兆秒。这些共同添加的光谱来自从凯克天文台档案馆（KOA）以原始形式获得的2753个单独的类星体暴露，并使用通过XIDL分布提供的数据减少包进行了均匀处理。 DR3可公开提供社区，作为KOA和IGMSPEC数据库中的高级科学产品。
We present and make publicly available the third data release (DR3) of the Keck Observatory Database of Ionized Absorption toward Quasars (KODIAQ) survey. KODIAQ DR3 consists of a fully-reduced sample of 727 quasars at 0.1 < z < 6.4 observed with ESI at moderate resolution (4000 < R < 10000). DR3 contains 872 spectra available in flux calibrated form, representing a sum total exposure time of approximately 2.8 megaseconds. These co-added spectra arise from a total of 2753 individual exposures of quasars taken from the Keck Observatory Archive (KOA) in raw form and uniformly processed using a data reduction package made available through the XIDL distribution. DR3 is publicly available to the community, housed as a higher level science product at the KOA and in the igmspec database.
