2. Introduction
Project: to analyze data collected by the Green Bank telescope and search for pulsars
Goals:
Identify known pulsars, RFI, and new pulsars
Investigate variations in periods
Sort noise from significant data

5. Radio Frequency Interference (R.F.I)
Documented in Rogue Gallery as a power line
Period ~ 1198 ms

6. Known Pulsar J1610-1322 Comparisons:
RA and Dec changed slightly from known pulsar in catalogue
~ no change in DM
Gunner

7. GBT Candidates Never before seen at 800 MHz.
Not in ATNF
New pulsar, named J in new drift scan data
Never before seen at 800 MHz.
Strong pulse profile against noise.
Anna D

8. 2013-0650 Comparison Little period change Much clearer lines.
In 2007 it was observed at a frequency of 350 MHz and now it was observed at a frequency of 800 MHz.
Little period change
Anna

9. GBT Candidates Strong vertical lines in the Sub-band Plot.
Low probability of noise.
Definitely not a known pulsar.
Erin

10. GBT Comparison Investigation looks more like RFI than 2007 data
We were very disappointed.
No period change
Erin

11. Conclusions Certainties Uncertainties/Questions
About 30 plots with extremely close DM values
RFI is present in almost half of the plots examined (47%)
Saw 3 known pulsars
Uncertainties/Questions
Could harmonics be different pulsars?
Why is there a difference when the pulsar was observed at 350 MHz and 800 MHz? What can we learn about the pulsar?
