论文摘要

径向速度实验（Rave）是对随机在南半球随机选择的银河恒星的幅度限制（9 <i <12）。 RAVE中分辨率光谱（R〜7500）覆盖了Ca-Triplet区域（8410-8795a）。第6个也是最终数据发布（DR6或FDR）基于451783独特恒星的518387观测值。在2003年4月12日至2013年4月4日之间进行了狂欢观察。在这里，我们介绍了Rave DR6中所有观察结果的狂欢的起源，设置和数据降低以及波长量化和磁通范围的光谱和误差光谱。此外，我们为Rave目标提供了派生的光谱分类和径向速度，并与Gaia DR2和其他相关目录相匹配。内部误差估计值的比较，从一个以上观测到的恒星得出的差异以及与GAIA DR2的径向速度的比较始终表明，有68％的物体具有比1.4 km/s更好的速度精度，而95％的物体的速度比4.0 km/s更好。随后的出版物中介绍了恒星大气参数，丰度和距离。可以通过Rave Web（http://rave-survey.org）或Vizier数据库访问数据。

The Radial Velocity Experiment (RAVE) is a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars randomly selected in the southern hemisphere. The RAVE medium-resolution spectra (R~7500) cover the Ca-triplet region (8410-8795A). The 6th and final data release (DR6 or FDR) is based on 518387 observations of 451783 unique stars. RAVE observations were taken between 12 April 2003 and 4 April 2013. Here we present the genesis, setup and data reduction of RAVE as well as wavelength-calibrated and flux-normalized spectra and error spectra for all observations in RAVE DR6. Furthermore, we present derived spectral classification and radial velocities for the RAVE targets, complemented by cross matches with Gaia DR2 and other relevant catalogs. A comparison between internal error estimates, variances derived from stars with more than one observing epoch and a comparison with radial velocities of Gaia DR2 reveals consistently that 68% of the objects have a velocity accuracy better than 1.4 km/s, while 95% of the objects have radial velocities better than 4.0 km/s. Stellar atmospheric parameters, abundances and distances are presented in subsequent publication. The data can be accessed via the RAVE Web (http://rave-survey.org) or the Vizier database.
