LOFAR in interferometric mode
Challenges in calibration and imaging
A-Team sources
Problematic RFI at low frequencies
Typical high band pre-processing ● Observations are taken
● 488 subbands 110-190 MHz● 1 second integration time● 64 channels per subband
FlaggingDemixing (A Team)Averaging
● Observations are made available● 488 subbands 110-190 MHz● 5 second integration time● 4 channels per subband
Data volume reduced from > 200 TB to about 3-4 TBIf you want to keep the original data you need to request it!
