cds-question@unistra.frinterferometryradio-galaxiesgalaxy-classification-systemsThe Boolardy Engineering Test Array is a 6x12m dish interferometer and the prototype of the Australian Square Kilometre Array Pathfinder (ASKAP), equipped with the first generation of ASKAP's phased array feed (PAF) receivers. These facilitate rapid wide-area imaging via the deployment of simultaneous multiple beams within an ~30deg^2^ field of view. By cycling the array through 12 interleaved pointing positions and using nine digitally formed beams, we effectively mimic a traditional 1hx108 pointing survey, covering ~150deg^2^ over 711-1015MHz in 12h of observing time. Three such observations were executed over the course of a week. We verify the full bandwidth continuum imaging performance and stability of the system via self-consistency checks and comparisons to existing radio data. The combined three epoch image has arcminute resolution and a 1{sigma} thermal noise level of 375{mu}Jy/beam, although the effective noise is a factor of ~3 higher due to residual sidelobe confusion. From this we derive a catalogue of 3722 discrete radio components, using the 35 per cent fractional bandwidth to measure in-band spectral indices for 1037 of them. A search for transient events reveals one significantly variable source within the survey area. The survey covers approximately two-thirds of the Spitzer South Pole Telescope Deep Field. This pilot project demonstrates the viability and potential of using PAFs to rapidly and accurately survey the sky at radio wavelengths.2016MNRAS.457.4160Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/457/4160CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/457/4160https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/457/4160http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/457/4160https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/457/4160https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/457/4160http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/457/4160GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/457/4160/table3 (Source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/457/4160/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/457/4160/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/457/4160/table3?GETtext/xml+votable180.050000true336.7591-52.55620.0055555555555555564/2845 2882-2883 2886-2889 2892 5/11359 11523 11526-11527 11538 11564-11565 11572 11576 6/45429-45431 45433-45435 45509 45511 45517 46087 46089 46091 46098-46099 46102 46158-46159 46170-46171 46174 46240-46241 46244-46245 46247 46269 46292-46294 46296-46297 46308 46312-46313 46369-46371 46376-463785.7182978780384475e-25 5.7182978780384475e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/457/4160?format=asciiOpticalRadiodefaultJ/MNRAS/457/4160/table3Source catalogrecnoRecord number assigned by the VizieR team.
