Comments

Pigyback search from upgraded Gregorian feed platform at Arecibo Observatory, similar to previous versions of SERENDIP. It ran with around the clock observation. 40 spectrum analysis/post-processing boards worked at the same time. The calculated power spectra was normalized with an 8000 channel boxcar. Every five seconds, the telescope's pointing coordinates were taken. The spectra was calculated and the normal slew rates were passed on. Any RFI was removed. Algorithms detected signal patterns, persistence, pulsing, and high-power events. SERENDIP IV looked for persistence in frequency over time. Candidates were reobserved.
