Here other algorithms are applied to the data to reject further noise. The possible candidates that remain after all the processing is done are added to a database. These candidates will be examined at a later date with a targeted search. Lower frequencies are to the left, higher frequencies are to the right. The height of the spikes gives the strength of the signal.
Recent readings are in front, past readings move to the rear.
Please note that these are the raw signals before processing. Once the signals are processed, all of the local sources of interference are thrown out. First, the discoverer must make all possible attempts to verify that the signal is indeed extraterrestrial. Then the discoverer can notify others in the field to obtain an independent verification of the discovery. If this test is passed, the discoverer can then broadly disseminate the information to the scientific community, the Secretary General of the United Nations, and the public.
