CORNISH-South Survey and Catalogue
Listed in IVOA Registry (Virtual Observatory)
We present the first high spatial resolution radio continuum survey of the southern Galactic plane.
Description
The CORNISH project has mapped the region defined by 295{deg}<l<350{deg}; |b|<1{deg} at 5.5-GHz, with a resolution of 2.5" (FWHM). As with the CORNISH-North survey, this is designed to primarily provide matching radio data to the Spitzer GLIMPSE survey region.
The CORNISH-South survey achieved a root mean square noise level of ~0.11mJy/beam, using the 6A configuration of the Australia Telescope Compact Array (ATCA). In this paper, we discuss the observations, data processing and measurements of the source properties. Above a 7{sigma} detection limit, 4701 sources were detected, and their ensemble properties show similar distributions with their northern counterparts.

The catalogue is highly reliable and is complete to 90 per cent at a flux density level of 1.1mJy. We developed a new way of measuring the integrated flux densities and angular sizes of non-Gaussian sources. The catalogue primarily provides positions, flux density measurements and angular sizes.
All sources with IR counterparts at 8{mu}m have been visually classified, utilizing additional imaging data from optical, near-IR, mid-IR, far-IR and sub-millimetre galactic plane surveys. This has resulted in the detection of 524 HII regions of which 255 are ultra-compact HII regions, 287 planetary nebulae, 79 radio stars and 6 massive young stellar objects. The rest of the sources are likely to be extra-galactic.
These data are particularly important in the characterization and population studies of compact ionized sources such as UCHII regions and PNe towards the Galactic mid-plane.
