   GLEAM (GaLactic and Extragalactic All-sky MWA (Survey)) Write:<<GLEAM JHHMMSS+DDMMSS>> N: about 350000  (SIMBAD class: Radio = Radio Source) Note:This is the extragalactic radio catalogue from the first year of the GaLactic and Extragalactic All-sky MWA survey, covering almost the entire sky south of Dec +30, to a 5-sigma limit of about 50 mJy at 200MHz. Excluded regions are the Galactic Plane, the Magellanic Clouds, areas around three bright sources, and a small area of the North where ionospheric conditions were unfavourable. The catalogue contains measurements for each source in 20 7.68-MHz sub-bands from 72 to 231 MHz, as well as a fiducial 200-MHz measurement using a 60-MHz bandwidth deep combined image. The resolution is approximately 2 arcminutes; position precision is dominated by ionospheric conditions and we estimate our astrometry to be good to 3 arcsec in the main survey region of -75 < Dec < 20, and 10 arcsec outside this region. Notes:The existing publication is the survey description paper: http://arxiv.org/abs/1505.06041, and there will be a paper published specifically devoted to this catalogue in either late 2015 or early 2016. There will then be further publications using more data, or dealing with currently-excluded regions of the sky.
