ATHDFS1P4G - Australia Telescope Hubble Deep Field-South 1.4-GHz Source Catalog |
HEASARC Archive |
The 1.4 GHz observations were carried out by the Australia Telescope Compact Array over 4 years from 1998 to 2001. They consist of single pointings centered on RA (J2000.0) = 22h 33m 25.96s, Dec (J2000.0) = -60o 38' 09.0".
Radio observations of the Hubble Deep Field-South region. II. The 1.4 GHz catalog and source counts. Huynh M.T., Jackson C.A., Norris R.P., Prandoni I. <Astron. J., 130, 1373-1388 (2005)> =2005AJ....130.1373H
Source_Number
A unique identification number for each radio source in the
catalog.
Alt_Name
An alternative source designation recommended by the CDS
Dictionary of Nomenclature of Celestial Objects using the prefix '[HJN2005]
1.4GHz' for Huynh, Jackson, Norris 2005 1.4-GHz, and the source number,
e.g., '[HJN2005] 1.4GHz 1'.
Name
The source designation as given in the reference paper using the
prefix 'ATHDFS' for Australia Telescope Hubble Deep Field-South together with
the J2000.0 equatorial coordinates of the source, e.g.,
'ATHDFS JHHMMSS.s+DDMMSS'.
RA
The Right Ascension of the radio source in the selected equinox. The RA
was given in J2000.0 coordinates to a precision of 0.01 seconds of time in the
original table.
RA_Error
The 1-sigma error in the Right Ascension of the radio source, in
arcseconds, calculated following Condon (1997, PASP, 109, 166) and Prandoni et
al. (2000, A&AS, 146, 41).
Dec
The Declination of the radio source in the selected equinox. The RA
was given in J2000.0 coordinates to a precision of 0.1 arcseconds in the
original table.
Dec_Error
The 1-sigma error in the Declination of the radio source, in
arcseconds, calculated following Condon (1997, PASP, 109, 166) and Prandoni et
al. (2000, A&AS, 146, 41).
LII
The Galactic Longitude of the radio source.
BII
The Galactic Latitude of the radio source.
Flux_1p4_GHz
The 1.4-GHz peak flux density of the radio source, in milliJansky per beam
(mJy/beam). The values given here are not corrected for the systematic
effects described in Section 3 of the reference paper. The Appendix in the
paper describes how to obtain source peak flux densities corrected for the
systematic effects.
Int_Flux_1p4_GHz
The 1.4-GHz integrated flux density of the radio source,
in milliJansky (mJy).
Major_Axis
The deconvolved major axis (FWHM) of the Gaussian fit to the radio source, in
arcseconds. Zero values refer to unresolved sources (see Section 4.3 of the
reference paper).
Minor_Axis
The deconvolved minor axis (FWHM) of the the Gaussian fit to the radio
source, in arcseconds. Zero values refer to unresolved sources (see Section
4.3 of the reference paper).
Position_Angle
The deconvolved position angle of the the Gaussian fit to
the radio source, in degrees, measured from North through East. Zero values
refer to unresolved sources (see Section 4.3 of the reference paper).
SNR_1p4_GHz
The signal-to-noise ratio of the radio source detection,
calculated as the ratio of the fitted peak flux density from the Miriad
task imsad to the local noise.
Fit_Quality_Flag
The Gaussian fit quality flag where '1' refers to very
good fits, '2' refers to poor integrated flux density, and 'n' refers to
non-Gaussian sources. See Section 4.2 of the reference paper for more details.
Assoc_Name_1
This parameter lists the name of any other radio source
associated with this source; components of a multiple source are indicated
with the name of the other source(s) with which they are associated. See
Section 4.4 of the reference paper for more details.
Assoc_Name_2
This parameter lists the name of yet another radio source
associated with this source; components of a multiple source are indicated
with the name of the other source(s) with which they are associated. See
Section 4.4 of the reference paper for more details.
