CATS数据库的当前状态
Current status of the CATS database
摘要：
我们描述的CATS，一个公开访问的数据库（Web服务器http://cats.sao.ru），允许一个搜索在数百个目录中发现的天体沿电磁波谱的当前状态。我们的重点主要放在从30到15000 MHz观测到的射电连续谱源的目录上，其次是射电和活动星，行星状星云，HII区，超新星遗迹（SNR），恒星，邻近星系，活动星系核和类星体等天体的目录。CATS还包括来自最大的河外巡天的星表，如NVSS，FIRST，WENSS，VLSS，TXS，GB 6，SUMSS，IRAS，2 MASS，SDSS，ROSAT，PGC，MCG等。2004年，CATS包括来自射电，红外，光学和X射线窗口的400多个星表的$\sim10^9$记录，包括大多数RATAN-600星表。CATS正在扩大和更新，包括新出版的目录以及我们首次以电子形式创建的旧目录。本文介绍了天体物理目录数据库的组织原则和CATS的主要功能。
英文摘要：
We describe the current status of CATS, a publicly accessible database (web-server http://cats.sao.ru) allowing one to search in hundreds of catalogs of astronomical objects discovered all along the electromagnetic spectrum. Our emphasis is mainly laid on catalogs of radio continuum sources observed from 30 to 15000 MHz, secondly on catalogs of objects such as radio and active stars, planetary nebulae, HII regions, supernova remnants (SNR), pulsars, nearby galaxies, AGN and quasars. CATS also includes the catalogs from the largest extragalactic surveys, like NVSS, FIRST, WENSS, VLSS, TXS, GB6, SUMSS, IRAS, 2MASS, SDSS, ROSAT, PGC, MCG, etc. In 2004 CATS comprised a total of $\sim10^9$ records from over 400 catalogs in the radio, IR, optical and X-ray windows, including most of RATAN--600 catalogs. CATS is being expanded and updated, both with newly published catalogs as well as older ones which we have created in electronic form for the first time. We describe the principles of organization of the database of astrophysical catalogs and the main functions of CATS.
