1. Online Session 2: Pulsar Data, Part 2 Sue Ann Heatherly Sarah Scoles

2. Tonight Questions or comments from pulsar webquest Questions or comments about website editing CLEA Pulsar Simulation Software

3. CLEA Software Try atnf: http://pulseatparkes.atnf.csiro.au/pulsardistance/ After you've installed the software (ignoring any errors that pop up), click File → Login.

4. CLEA: Radio Astronomy of Pulsars The page for the pulsar lab will appear. Click File → Run → Radio Telescope.

5. CLEA: Known Pulsars To look at a known pulsar, turn Tracking on; click “Hot List” and select the pulsar; confirm that you would like to move the telescope.

6. CLEA: Coordinates To observe a specific location, click “Set Coordinates” and type in the RA and Dec

7. CLEA: Taking Data Once the telescope is in place, you can start to observe. Click “Receiver.” To start taking data, click “Mode.” The x-axis of the data is time, and the y-axis is radio strength. By clicking, “Add Channel,” you can make the telescope observe the pulsar using multiple set-ups.

8. CLEA: Data Analysis “Freq” changes the frequency being observed “Freq incr” is the amount by which you change the frequency “Horz secs” is the amount of time shown on the x- axis “Vert gain” controls the radio “magnification”
