Pulsar search candidates:
The input data to SDP pulsar search will consist of a large number of pulsar search candidates, up to 1,500,000 per scan (i.e. pulsar observation). The pulsar search candidates, with each candidate’s associated metadata, S/N sheets and datacube is collectively known as an Optimised Candidate List and Data (OCLD), with one OCLD generated per beam per scan, typically once every 180 - 1800 seconds.
There shall be 1000 optimised candidate data cubes stored in an OCLD (as there are expected to be 1000 sifted candidates per beam) and these are accompanied by their metadata. There are less optimised/sifted candidates than those listed in the candidate list , as only the most promising candidates have their data propagated by CSP. All optimised/sifted candidates shall also be listed in the candidate list. See Figure 3 and Figure 4 for models of the Pulsar Search data.
