CASA task to quickly inspect a measurement set for RFI by plotting time vs frequency vs amplitude.
plot3d is designed to retain peak amplitudes of RFI spikes while performing data compression to speed up plotting. Your measurement set remains read-only throughout the task. If your data contains multiple scans, gaps between scans will be reset to 5 integration timescales.
