保护VO的新旧日志表：河外和射电数据的状况
Safeguarding Old and New Journal Tables for the VO: Status for Extragalactic and Radio Data
摘要：
独立于已建立的数据中心，部分是为了我自己的研究，自1989年以来，我一直在收集2600多篇关于射电源和河外天体的文章的表格数据。光学字符识别（OCR）被用来恢复表从740份文件。在CDS或CATS目录集合中，2600篇文章中只有41%的表格可用，NED数据库的覆盖率估计只有稍微好一点。这一比例对于2001年以来以电子方式发表的文章来说并不好。需要查阅天体数据库（NED、SIMBAD、LEDA）以及目录浏览器（VizieR、CATS），以获得关于天文天体的最完整信息。数据中心需要更多的人力资源，作者、审稿人、编辑、出版商和数据中心之间需要更好的合作，以提高数据的覆盖率和可访问性。目前在虚拟观测站项目范围内所作的努力是为储存在不同地点的不同类型的已公布和档案数据提供检索和分析工具，在这方面，应当作出同等努力，恢复和纳入目前无法以这种方式获得的大量已公布数据。
英文摘要：
Independent of established data centers, and partly for my own research, since 1989 I have been collecting the tabular data from over 2600 articles concerned with radio sources and extragalactic objects in general. Optical character recognition (OCR) was used to recover tables from 740 papers. Tables from only 41 percent of the 2600 articles are available in the CDS or CATS catalog collections, and only slightly better coverage is estimated for the NED database. This fraction is not better for articles published electronically since 2001. Both object databases (NED, SIMBAD, LEDA) as well as catalog browsers (VizieR, CATS) need to be consulted to obtain the most complete information on astronomical objects. More human resources at the data centers and better collaboration between authors, referees, editors, publishers, and data centers are required to improve data coverage and accessibility. The current efforts within the Virtual Observatory (VO) project, to provide retrieval and analysis tools for different types of published and archival data stored at various sites, should be balanced by an equal effort to recover and include large amounts of published data not currently available in this way.
