Because the signals of radio pulsars are not sinusoidal but pulsed, the frequency analysis will show frequency components at the fundamental frequency (the intrinsic spin frequency) and at higher harmonics (integer multiples of the fundamental frequency). Summing these components is a well-known trick in pulsar searches and significantly increases the sensitivity of the search. This summation is the last step done on the users' computers. Finally a list of the most significant candidates is reported back to the Einstein@Home servers and analyzed by the project scientists. | Because the signals of radio pulsars are not sinusoidal but pulsed, the frequency analysis will show frequency components at the fundamental frequency (the intrinsic spin frequency) and at higher harmonics (integer multiples of the fundamental frequency).

Using the combined computing power of 200,000 volunteer PCs, Einstein@Home discovered '''24 new pulsars''' in archival data from the [[wikipedia:Parkes Observatory|CSIRO Parkes radio telescope]] in Australia. These included 18 isolated pulsars and 6 in binary systems, some with orbital periods of only a few hours. The results were published in ''The Astrophysical Journal''.<ref>{{cite journal|title=Einstein@Home Discovery of 24 Pulsars in the Parkes Multi-beam Pulsar Survey|journal=The Astrophysical Journal|volume=774|issue=2|year=2013|author=B.
