<i>In situ</i> measurement of MWA primary beam variation using <i>ORBCOMM</i>
Abstract We provide the first in situ measurements of antenna element beam shapes of the Murchison Widefield Array. Most current processing pipelines use an assumed beam shape, which can cause absolute and relative flux density errors and polarisation āleakageā. Understanding the primary beam is then of paramount importance, especially for ā¦
