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.

CLEA: Radio Astronomy of Pulsars

The page for the pulsar lab will appear.

Click File → Run → Radio Telescope.

CLEA: Known PulsarsTo look at a known pulsar,

turn Tracking on;

click “Hot List” and select the pulsar;

confirm that you would like to move the telescope.

CLEA: Coordinates

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

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.

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”
