The PulsarsThe Pulsars
In all, we found 6 pulsars In all, we found 6 pulsars 3 of them were already in the ATNF 3 of them were already in the ATNF

Conclusion:Conclusion:
94% of all the Pulsar data sheets were RFI 94% of all the Pulsar data sheets were RFI and/or background noise. There were still and/or background noise. There were still a couple possible pulsars that we found.a couple possible pulsars that we found.
Of the possible Candidate Pulsars, there Of the possible Candidate Pulsars, there were 3 that were identified as already were 3 that were identified as already existing pulsars, while there were also 3 existing pulsars, while there were also 3 that were unidentified.that were unidentified.
