无线电交叉识别和频谱的SPECFIND V2 .0目录。SPECFIND与虚拟天文台相遇
The SPECFIND V2.0 catalogue of radio cross-identifications and spectra. SPECFIND meets the Virtual Observatory
摘要：
介绍了新发布的SPECFIND无线电交叉识别目录SPECFINDV2.0。它包含107488个交叉识别的物体，至少有三个无线电源在三个独立的频率观察。与上一期相比，入门无线电目录的数目从20个增加到97个，其中包括115个表格。这一大幅度的增长是由于CDS开发了四种工具才得以实现的，这些工具使用了虚拟天文台的标准和基础设施。这是在VO-TECH第六框架计划欧洲设计研究的框架内完成的。我们给出了用户可能遇到的不同类别的无线电源的概述。由于增加了输入无线电目录的频率覆盖范围，该版本表明SPECFIND算法能够检测到约1 GHz频率的频谱中断。
英文摘要：
The new release of the SPECFIND radio cross-identification catalogue, SPECFIND V2.0, is presented. It contains 107488 cross-identified objects with at least three radio sources observed at three independent frequencies. Compared to the previous release the number of entry radio catalogues is increased from 20 to 97 containing 115 tables. This large increase was only made possible by the development of four tools at CDS which use the standards and infrastructure of the Virtual Observatory (VO). This was done in the framework of the VO-TECH European Design Study of the Sixth Framework Program. We give an overview of the different classes of radio sources that a user can encounter. Due to the increase of frequency coverage of the input radio catalogues, this release demonstrates that the SPECFIND algorithm is able to detect spectral breaks around a frequency of ~1 GHz.
