Abstract
One of the challenges in the design of the LOFAR radio telescope is
the calibration of the ionosphere, which can change within minutes
and can vary over the field of view. To reduce the number of
unknown parameters a specific model of the ionospheric corruptions
is needed. In this presentation we will discuss LOFAR
self-calibration using the Measurement Equation in general and
ionospheric calibration in more detail.
