Zusammenfassung der Projektergebnisse

We worked successfully on a wide range of topics within the Low Frequency Array (LOFAR) collaboration and made a lasting impact on the entire field. The work went far beyond the goals that we had initially designated for project. In particular, we set out to calibrate the polarisation in LOFAR observations and searched for polarised sources in the Tier-I survey.
