论文摘要
我们基于18,146个测得的速度，在12h 43mn 00s <R.A.之间，基于18,146个测量的速度，向沙普利超集团区域提供了一个数据库和速度目录。 <14h 17mn 00和-23°30'00“ <dec <-38°30'00”。数据目录包含从发现到2015年的文献的速度。它还包括5,084个速度，对应于4,617个星系，我们在LAS Campanas和CTIO观测站观察到，直到现在直到现在。其中，有2,585个对应于2015年前没有其他先前发表的速度测量的星系。速度数据库中的每个星系都已经鉴定出了从超级群体光度计目录中提取的星系。我们还为所有10,719个星系提供了测量速度的所有10,719个星系的组合平均速度目录，采用超级镜头位置作为均匀的基础。采用了R2 = 18.0 mag的一般级截止（仅针对一些新的报道速度例外）。总的来说，我们确认了夏普利超级收集器的整体结构，如前一篇论文所示。但是，更广泛的速度数据显示了更精细的结构，将在未来的出版物中进行讨论。
We present a database and velocity catalogue towards the region of the Shapley Supercluster based on 18,146 measured velocities for 10,719 galaxies in the approximately 300 square degree area between 12h 43mn 00s < R.A. < 14h 17mn 00s and -23° 30' 00" < Dec < -38° 30' 00". The data catalogue contains velocities from the literature found until 2015. It also includes 5,084 velocities, corresponding to 4,617 galaxies, observed by us at Las Campanas and CTIO observatories and not reported individually until now. Of these, 2,585 correspond to galaxies with no other previously published velocity measurement before 2015. Every galaxy in the velocity database has been identified with a galaxy extracted from the SuperCOSMOS photometric catalogues. We also provide a combined average velocity catalogue for all 10,719 galaxies with measured velocities, adopting the SuperCOSMOS positions as a homogeneous base. A general magnitude cut-off at R2=18.0 mag was adopted (with exceptions only for some of the new reported velocities). In general terms, we confirm the overall structure of the Shapley Supercluster, as found on earlier papers. However, the more extensive velocity data show finer structure, to be discussed in a future publication.
