Description:
The ATESP survey is a radio survey accomplished with the Australia
Telescope Compact Array (ATCA) at 1.4 GHz over a region of 26 square
degrees centered at -40 and ranging in RA from 22h30m to 01h15m. The
survey consists of 16 radio mosaics with 8x14 arcsec resolution and
uniform sensitivity (1 sigma noise = 79 microJy). The final 6 sigmas
catalogue contains 2960 sources down to a detection limit of 0.5 mJy.
This region is superposed to the redshift survey ESO Slice Project
(ESP) and is partly covered by the EIS survey (Patch A; see Cat.
J/A+AS/130/323).
Table 3 summarizes the main parameters for the final 16 mosaics: for
each mosaic are listed the number of fields composing it (columns x
rows), the tangent point (sky position used for geometry calculations)
and the synthesized beam (size and position angle). The spatial
resolution can vary from mosaic to mosaic depending on the particular
array (6A, 6C or 6D) used in the observations. The mean value for the
synthesized beam is 8"x14".
The last three columns of Table 3 show the results of the noise
analysis. For each mosaic we report the minimum (negative) flux
(S_min) recorded on the image (typically |S_min| is of the order of
0.5 mJy, corresponding to the value at which we have stopped the
cleaning) and the noise level. This has been evaluated either as the
FWHM of the Gaussian fit to the flux distribution of the pixels (in
the range ±S_min), in order to check for correlated noise
(sigma_fit), or as the standard deviation of the average flux in
several source-free sub-regions of the mosaics, in order to verify
uniformity ().
