RADIO - Master Radio Catalog


Overview

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. 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.

Provenance

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.

Parameters

Name
The source designation in the originating database.

Database_Table
The originating database table.

RA
The Right Ascension of the radio source.

Dec
The Declination of the radio source.

LII
The Galactic Longitude of the radio source.

BII
The Galactic Latitude of the radio source.

Flux_20_cm
The radio flux density at 20 cm (defined as lying in the frequency range from 1390 to 1670 MHz) in mJy, or, in a few cases, mJy/beam. For single-dish surveys such as NORTH20CM and PKSCAT90, the quoted values are essentially in mJy. For most surveys carried out with interferometric telescopes such as the VLA, e.g., FIRST, WBHGP20CM, WBHGP6CM, NVSS and VLANEP, we have selected the integrated flux density of the source (in mJy) rather than the peak flux density (in mJy/beam). The data entries and documentation for the original database tables should be examined for more detailed information.

Flux_20_cm_Error
The estimated error in the radio flux density at 20 cm, in mJy, or, in a few cases, mJy/beam. For entries from the FIRST Catalog, this is the local rms noise estimate at the source position, and does not include any additional error for spatially extended sources.

Flux_6_cm
The radio flux density at 6 cm (defined as lying in the frequency range from 4500 to 5050 MHz) in mJy, or, in a few cases, mJy/beam. For single-dish surveys such as NORTH6CM, NORTH20CM and PKSCAT90, the quoted value is essentially in mJy. For entries from the WBHGP6CM and PMN Catalogs, we have selected the integrated flux density of the source (in mJy) rather than the peak flux density (in mJy/beam). The data entries and documentation for the original database tables should be examined for more detailed information.

Flux_6_cm_Error
The estimated error in the radio flux density at 6 cm, in mJy.

Flux_Other
The radio flux density at a wavelength other than 6 or 20 cm, in mJy, or mJy/beam. For entries from the WENSS and SUMSS Catalogs, we have selected the integrated flux density of the source (in mJy) rather than the peak brightness or flux density (in mJy/beam), notice. The original databases should be examined for the latter information. The particular wavelength to which the quoted flux density corresponds is a function of which particular component database the entry comes from:

Note that, in a few cases in MOSTSNRCAT, some quoted values are lower limits to the actual integrated flux density. Refer to the original catalog for more information.

Flux_Other_Error
The estimated error in the radio flux density at the particular wavelength to which the flux_other parameter corresponds, in mJy, or, in a few cases, mJy/beam. For entries from the WENSS catalog, this is the local rms noise estimate at the source position, and does not include any additional error for spatially extended sources.
