  1. Team Parkes PSC 2011

  2. Introduction • Team Parkes folded the experiences and information imparted by PSC instructors, scientists, and mentors to establish a method of attacking the data most efficiently and to answer the question, “Is it a pulsar or is it Memorex?” Team Parkes’ members determined the most effective approach to analyze data sets. During this initial phase of the data analysis process, team members rated plots. When a plot scored two or higher, the entire team was assembled for input. Team Parkes studied the interesting plots making a final determination. Team members shared data sets to speed the process. Of all the data sets analyzed, five plots were flagged as worthy of further investigation.

  3. Every team member used Duncan’s Pulsar technique (or some form of it) Dunc’s Rule of Thumb reduced x2 < 1 bad reduced x2 < 2 (≈ pulsar/RFI) reduced x2 > 3 (pulsar/RFI) Image taken from : http://physics.wvu.edu/people/duncan_lorimer Divide and Conquer The Man, the Myth, the Legend… Duncan Lorimer

  4. Time Domain Plot: Are there average pulses? 2. Integrated Pulse Profile: Do the pulses match the Time Domain Plot? 3. Sub-band Plot: Vertical or Horizontal line? (Vertical = possible pulsar, Horizontal = RFI) 4. DM curve: look for a peak > 0 5.

  13. Discussion Points Certain • Sift through “stuff” to get to a possible candidate • GBT malfunctioned • GBT was working some of the time • Good potential candidates • Ton of noise Uncertain • If any of our candidates are pulsars • Data would have been gathered • When malfunction began during our scan • Confirmation • Causes other than RFI?

  14. Are the plots that we didn’t get to run pulsars? Will they/when will they be followed up? If so, we will be notified. In the future, time permitting, we would run all of our candidates.
