Abstract

We present the first results from the Phoenix Deep Survey, a multiwavelength survey of a 2 deg diameter region. Observations in the radio continuum at 1.4 GHz carried out with the Australia Telescope Compact Array are described. The catalogue of over 1000 radio sources compiled from these observations is analysed, and the source counts are presented. We model the observational source counts using a two-population model and published luminosity functions for these populations. Upon invoking luminosity and density evolution, we find that a luminosity evolution model best fits the radio observations, consistent with earlier work. The redshift distribution of the two galaxy populations investigated is also modelled and discussed.

Column Descriptions

* Catalogue number: Objects are numbered in order of increasing 1.4 GHz right ascension.

* 1.4 GHz R.A. and Dec.: Position of the radio source in J2000.

* bmaj, bmin, pa: Major and minor axes, and position angle of the radio source (convolved with the beam size - which is about 8x10 arcsec (in the RAxDec sense) for objects from field 1 (see "field" below) and about 5.5x6.5 arcsec for others).

* 1.4 GHz flux density: Radio source flux density in millijanskys.

* R-band R.A. and Dec.: Position of the optical counterpart to the radio source, again in J2000.

* R, V, B, H, K mags: The apparent brightness in the respective optical or near-infrared wavelength band. The B-band magnitudes come from the COSMOS database, the rest from observations made specifically for this survey.

* Focas2 Class: s, g, or f, indicating object has been identified as a star, galaxy or too faint to be distinguished by the classifier, respectively.

* F: The fractional chance that the optical counterpart has been mis-identified.

* dist: The distance (in arcsec) between the radio and optical source positions.

* z: The spectrally identified (geocentric) redshift of the optical galaxy. accuracy +-0.001

* Rel.: The "reliability" of the redshift, based on the quality of detected lines in the spectrum. 1 indicates very reliable (redshift based on two or more well-identified lines), 2 indicates less reliable (redshift based on one line only, or on two less certain lines), and 3 indicates unreliable (redshift based on lines or features which are uncertain).

* Spectral class: This is simply to distinguish between starburst and AGN type galaxies. Class A: Blue continuum with strong emission lines; Class AB: H-alpha present but H-beta only in noise, weaker emission line objects; Class B: Red continuum, moderate to strong H-alpha; Class C: Red continuum, absorption lines only; Class D: QSO (Broad emission line object at high redshift).

* Field: 1, 2, or 3, indicating whether the source was identified in the 2 degree diameter mosaic (PDF) only (1); the smaller, deeper observations (PDFS) only (2); or in both (3).

Get this table in other formats

* Postscript file (478k). This has a different layout to the html version, to facilitate printing on A4 pages. It is 55 pages long (and has been extracted directly from my thesis, so runs from pages 99 to 153, as of 11/06/98).

* Gzipped postscript file (110k). As above.

* Text file (148k). This has almost the same layout as the table presented here. The exceptions are the columns "Focas2 class", "F", and "dist", which appear (in the same order) between the "K mag" and "z" columns, and the column "Field" is absent. The FORTRAN format for the file is: i4,x,i,x,i2,x,f6.3,x,i3,x,i2,x,f5.2,3x,f4.1,2x,f4.1,x,f5.1,2x, f7.3,3x,i,x,i2,x,f5.2,2x,i3,x,i2,x,f4.1,x,f6.3,x,f6.3,x,f5.2,x,f4.1,x,f6.3, x,a,x,f5.3,2x,f5.3,x,f5.3,x,i,5x,i. * Gzipped text file (34k). As above.
