Limits of noise and confusion in the MWA GLEAM year 1 survey

The GaLactic and Extragalactic All-sky MWA survey (GLEAM) is a new relatively low resolution, contiguous 72-231 MHz survey of the entire sky south of declination +25. In this paper, we outline one approach to determine the relative contribution of system noise, classical confusion and sidelobe confu...
