LOFAR Overviews. Signals are digitized at a very early stage, making it a software-heavy facility. The signals recorded by the LOFAR stations are sent to the central processing facility at the University of Groningen’s supercomputer centre. The digital back end, named Cobalt, either correlates these data or creat

LOFAR Station Processing to stable and good quality scientific output products. The whole analogue and digital LOFAR station processing steps, from the antennas up to the optical fiber output signal, are explained in detail in this chapter.

Wide Field Imagingrast, images can be corrected in a direction dependent fashion. For example, an image can be adjusted to correct for the direction dependent sensitivity pattern of a primary antenna beam. However, this image-plane correction can only be properly applied if the beam is not time dependent. Effects tha

Polarization Imaging with LOFARger than at for example L band. The ionosphere in particular is a big nuisance. Moreover, the polarized response of (a group of) phased array stations is very different from the response of (a group of) parabolic dish antennas. This lecture focuses mainly on the physics of low frequency polarimetry,
