Overview

This table contains the 5-sigma catalog at 610 MHz of the VIMOS VLT Deep Survey-Very Large Array (VVDS-VLA) deep field obtained from Giant Metrewave Radio Telescope (GMRT) observations. The field is located at RA, Dec = 02:26:00, -04:30:00 (J2000) and covers a 1-square degree area.

The GMRT observations imaged the whole 1 square degree field with an angular resolution of 6 arcseconds and an average sensitivity of about 50 microJy/beam. The catalog lists 514 radio sources, 17 of which are fitted with multiple components (between 2 and 5). For these multiple sources, each component (A, B, etc.) is listed separately, and the entire source (indicated by the suffix T in the name) is also listed. Thus, there are 557 entries in this table, 43 of which correspond to multiple components.

Provenance

This table was created by the HEASARC in February 2012 based on CDS Catalog J/A+A/463/519 file table.dat.

Parameters

Name
The name of the radio source using the IAU-style designation for the source based on the truncated J2000.0 equatorial coordinates of its position, viz., 'VIRMOS 0.6GHz JHHMMSS-DDMMSSA', where the 'VIRMOS 0.6GHz' prefix stands for 'Visible and Infrared Multi-Object Spectrographs, 0.6 GHz source'. This naming convention has been registered with the CDS Dictionary of Nomenclature of Celestial Objects. The final character, if alphabetic, indicates that the source has multiple components: if 'A', 'B', 'C', 'D' or 'E', the listed properties refer to the specific component, while if 'T', the listed properties are for the complete composite source.

RA
The Right Ascension of the radio source in the selected equinox. This was given in J2000.0 equatorial coordinated to a precision of 0.01 seconds of time in the original table.

Dec
The Declination of the radio source in the selected equinox. This was given in J2000.0 equatorial coordinated to a precision of 0.1 arcseconds in the original table.

LII
The Galactic Longitude of the radio source.

BII
The Galactic Latitude of the radio source.

RA_Error
The error in the Right Ascension of the radio source, in arcseconds.

Dec_Error
The error in the Declination of the radio source, in arcseconds.

Flux_610_MHz
The peak brightness or flux density of the radio source at 610 MHz, in mJy/beam.

Flux_610_MHz_Error
The error in the peak brightness or flux density of the radio source at 610 MHz, in mJy/beam.

Int_Flux_610_MHz
The total (integrated) flux density of the radio source at 610 MHz, in mJy.

Int_Flux_610_MHz_Error
The error in the total (integrated) flux density of the radio source at 610 MHz, in mJy.

Major_Axis
The major axis of the radio source (if resolved), in arcseconds.

Minor_Axis
The minor axis of the radio source (if resolved), in arcseconds.

Position_Angle
The position angle of the major axis of the radio source, in degrees, measured from North towards East.

Resolved_Flag
This flag parameter is set to 'r' to indicate that the source is resolved, else to 'u' (for unresolved).
