Master Radio Catalog
Listed in NASA Data Portal
The RADIO database table is a periodically revised master catalog that contains selected parameters from a number of the HEASARC database tables that have information on radio source flux densities.
Description
The contents of this RADIO master catalog are listed in alphabetical order in the References section of this document. Each entry in RADIO has a parameter called `database_table` which indicates the originating database table from which the entry was copied.
Users should check out the original database table if they want to examine all of the parameters that are available in that particular database table for the particular source(s) in which they are interested. Two of the component database tables of RADIO, DIXON and KUEHR, are compilations of radio observations, and individual sources can have multiple entries, representing either observations at different frequencies or multiple observations at the same frequency.

In the latter case, notice, the flux density quoted in the RADIO database is an average of the individual flux densities at that particular frequency in the originating database. To see all of the individual entries for a source in RADIO from either of these two component databases, the corresponding entries in the DIXON and KUEHR database tables should be examined. The HEASARC in certain instances has included radio sources for which the quoted value for the specified band is an upper limit rather than a detection.
The HEASARC recommends that the user should always check the original tables to get the complete information about the properties of the sources listed in the RADIO master source list. This database table is periodically updated by the HEASARC whenever one of the component database tables is modified or a new component database table is added. This is a service provided by NASA HEASARC .
