Ionospheric calibration of low frequency radio interferometric observations using the peeling scheme
Ionospheric calibration of low frequency radio interferometric observations using the peeling scheme
Calibration of radio interferometric observations becomes increasingly difficult towards lower frequencies. Below <i>∼<i/>300 MHz, spatially variant refractions and propagation delays of radio waves traveling through the ionosphere cause phase rotations that can vary significantly with time, viewing direction and antenna location. In this article we present a description and first …
