Description

dreamBeam is used in the first attempt at polarization calibrating pulsar data collected with the international HBA stations. The results show that a standard pulsar calibration approach fails, due to the inaccurate corrections of the projection effects by dreamBeam. We propose this procedure as a test bench test for the new beam model proposed for LOFAR2.0
