ATHDFS Catalogue Description
The ATHDFS catalogues result from an analysis of the inner region of each of the four radio images. A radial distance limit was employed because the primary beam correction becomes very large towards the edges of the images.
The catalogue radial limits are:
* 20 arcmin (from centre, RA = 22 33 25.96, Dec = -60 38 09.0) at 1.4 GHz,
* 12 arcmin (from centre, RA = 22 33 25.96, Dec = -60 38 09.0) at 2.5 GHz
* 5.5 arcmin (from centre, RA = 22 32 56.22, Dec = -60 33 02.7) at 5.2 GHz and
* 3.5 arcmin (from centre, RA = 22 32 56.22, Dec = -60 33 02.7) at 8.7 GHz.
See Paper II for more details on the source extraction.
A description of the ASCII Tables is as follows:
Column (1) --- Source ID number Column (2) --- Source name. Different components of multiple sources are labeled A, B, etc.
Column (3) --- Right Ascension in J2000.
Column (4) --- One sigma uncertainty of Right Ascension, in arcsec.
Column (5) --- Declination in J2000.
Column (6) --- One sigma uncertainty of Declination, in arcsec.
Column (7) --- Source 1.4 GHz peak flux density, in mJy.
Column (8) --- Source 1.4 GHz integrated flux density, in mJy.
Column (9) and (10) --- The deconvolved major and minor axes (FWHM) of the source, in arcsec. Zero values refer to unresolved sources.
Column (11) --- The deconvolved position angle (PA, measured from N through E) of the source, in degrees. Zero values refer to unresolved sources.
Column (12) --- The signal-to-noise ratio of the detection.
Column (13) --- Gaussian fit flags: ``s'' refers to poor integrated flux density value (see Paper II), and ``n'' refers to non-Gaussian sources.
