Аннотация:
С 2011 г. база данных астрономических каталогов активно оснащается ПРАО АКЦ ФИАН http://as tro.prao.ru/db/ средствами визуализации данных и сравнения каталогов между собой. Данные средства будут служить основой для статистической обработки и перекрестного анализа различных астрономических каталогов. Для поставленных задач нами разрабатываются: средства графического отображения данных нескольких каталогов в пределах выбираемой площадки на небе; отображение данных и статистический анализ основных параметров каждого каталога в целом; статистика кросс-отождествлений избранных пользователем каталогов.

Abstract:
Pushchino Radio Astronomy Observatory ASC LPI has for several years been developing a database
of the major and most important astronomical catalogs most frequently used by radio astronomers.
These are survey catalogs of radio sources observed in various radio frequencies (and also frequencies
of other spectrums), catalogs of major heavenly objects studied in radio astronomy, etc.
The astronomical catalogs data is operating in on-line mode on the site called
"Radio-astronomer's working environment", http://astro.prao.ru/db/ .
It already contains some tens of the major astronomical catalogs. Starting
in 2011 the database has been actively equipped with means of graphical visualisation
of the data and cross-analysis of the catalogs among themselves. These means will serve
as the base for statistical processing and cross-analysis of various astronomical catalogs.
For example, catalogs of radio-sources on various frequencies can be widely used in further
theoretical and experimental research of properties of both extragalactic radiation sources
and objects in our own Galaxy. Statistical cross-analysis of the data from various catalogs
can be used both for research of properties of separate objects and for the statistical
analysis of properties of various classes of objects. It can also be used for research
of properties of the catalog data like completeness, reliability, calibration of catalogs etc.
For the tasks at hand we are developing tools for graphic representation of the data from several
catalogs within a chosen sector on the sky; representation of the data and the statistical analysis
of the main parameters
of each catalog; and statistics of cross-identifications of the catalogs selected by the user.
