Bright Eetragalactic Radio Sources at 2.7 GHz -III.
The all-sky catalogue

Wall J.V. & Peacock J.A.

Abstract

We catalogue the brightest extragalactic radio sources at 2.7 GHz. The complete sample comprises 233 sources found in the major centimetre- wavelength surveys carried out at ANRAO/Parkes, NRAO/Greenbank, and MPIfR/Bonn; the sample covers 9.81 sr and has limits S2.7=2.0 Jy and |b| >10^o. A critial re-analysis of the data shows that 227 (97%) have optical identificatrion and 171 (73 %) have measured Z. The implications of the catalogue statistics for the luminosity functions of different radio-source populations are considered.

Description

This catalog contains the brightest radio sources at 2.7 GHz. The complete sample comprises 233 sources found in the major centimeter-wavelength surveys carried out at ANRAO/Parkes, NRAO/Greenbank, and MPIfR/Bonn. The sample covers 9.81 sr and has a limit of 2.0 Jy at 2.7 GHz, with |b| > 10. These data were originally presented in Wall and Peacock, MNRAS, 216, 173.

Field List - Detailed Descriptions

1. COLUMNS iauname name

The iauname column gives the name of the source in IAU convention. The name column gives an alternative name, if available.
Example (iauname) (char7): '0320-37'
Example (name) (char8): 'For A'

2. COLUMNS ra_1950 dec_1950 ra_1950_deg dec_1950_deg

These columns give the B1950 right ascension and declination of the source. Positions are from the first reference listed in the "ref" column, and are optical positions with the following exceptions: if the optical position was of low accuracy and the source was compact, the radio position was used.
Example (ra_1950) (real): 0.876068
Example (dec_1950) (real): -0.652491
Example (ra_1950_deg) (real): 50.195000
Example (dec_1950_deg) (real): -37.384998

3. COLUMN poserr

This column gives the positional error. The quoted error is the rms in one direction in arcsec.
Example (poserr) (real): 4.0

4. COLUMN s_11cm

This column gives the flux density at 2.7 GHz, in Jy. The 2.7 GHz flux-density scale was changed from that used by Kellermann et al. (1969) to the Parkes flux-density scale.
Example (s_11cm) (real): 98.0

5. COLUMN alpha

This column gives the spectral index between 2.7 and 5 GHz, in the sense of S prop nu^(-alpha).
Example (alpha) (real): 0.52

6. COLUMN id

This column gives the optical classification of the source, as follows:

Q QSO confirmed by spectrum or variability (and including BL Lac objects).
Q? Stellar object on position.
G Galaxy confirmed by extended image.
G? Very faint object; presumed galaxy.
EF Empty field

Example (id) (char3): 'G'

7. COLUMN mv

This column gives the visual magnitude of the source.
Example (mv) (real): 7.0

8. COLUMNS z z_flag

These columns give the redshift and redshift flag. The z_flag column is marked with an asterisk ('*') if the redshift is an estimate.
Example (z) (real): 0.0008
Example (z_flag) (char1): '*'

9. COLUMN ref
