Understanding instrumental Stokes leakage in Murchison Widefield Array polarimetry by Sutinjo, Adrian, O'Sullivan, J., Lenc, E., Wayth, Randall, Padhi, S., Hall, Peter, Tingay, Steven

“…This paper offers an electromagnetic, more specifically array theory, perspective on understanding strong instrumental polarization effects for planar low-frequency "aperture arrays" with the Murchison Widefield Array (MWA) as an example. A long-standing issue that has been seen here is significant instrumental Stokes leakage after calibration, particularly in Stokes Q at high frequencies. …”
