Flagging strategy for the DSA-2000

The DSA-2000 radio telescope is a next generation interferometer with stringent requirements in terms of real-time processing, sensitivity, and data quality. Corrupted data need to be identified and excised in real-time from the data processing chain as the system architecture does not support the storage and accumulation of the data. This paper addresses the problem of efficient and fast data flagging for DSA-2000.
