This search allows users to search for observations taken from the Australia Telescope National Facility in Parkes using specific search criteria.
ATNF Pulsar Search
Users can use the following search fields to search for observations:
The pulsar's J name (position in the celestial sphere) that provides more precise coordinates of its location in the sky.
One of two coordinates (the other: declination) on the celestial sphere. Right ascension is the celestial equivalent of terrestrial longitude. Both right ascension and longitude measure an angle from a zero point on an equator. For right ascension, the zero point is known as the first point of Aries, which is the place in the sky where the Sun crosses the celestial equator at the March equinox. It is customarily measured in hours, minutes, and seconds, with 24 hours being equivalent to a full circle.
One of two coordinates (the other: right ascension) on the celestial sphere. Declination in astronomy is comparable to geographic latitude, but projected onto the celestial sphere. Declination is measured in degrees north and south of the celestial equator. Points north of the celestial equator have positive declinations, while those to the south have negative declinations.
Number of minutes of arc, forming a search radius from the central point.
An identification code given to observing projects granted time at the Parkes Observatory.
UTC (Coordinated Universal Time) / MJD (Modified Julian Date) start of the observation. (MJD: days from 17 November, 1858).
Search by the filename
Radio astronomy is a sub-field of astronomy that studies celestial objects at radio frequencies. This field is the centre frequency of the observation.
The wavelength of the centre frequency.
PSR: known pulsars recorded in fold mode. Search: Un-folded observations.
Name of the telescope digitising instrumentation used for the observation.
Name of the telescope receiver used for the observation.
The configure columns button allows the users to configure which columns and fields will be displayed in the search results page.
ATNF Pulsar Search Results
Please note that the files marked with a Data Access and Download.are not currently available for download. See
The ATNF search results appear in the following format:
This functionality allows users to go back to the search page with all the populated fields from the last search retained.
This functionality can be used to further filter on the search results by using some filter facets such as
- Source Name
- Project ID
- Observation Type
- Calibration Files
The configure columns functionality allows the users to configure which columns and fields will be displayed in the search results page.
ATNF Pulsar Data Access and Download
CSIRO's Data Access Portal holds many terabytes of pulsar observations with new data being added at the end of every semester. The observations that are not currently in high demand are stored in a tape library and not available for immediate access through the disc.
When an observation file in your search result is not currently available on disc it will have amark in the selection column.
To access the file:
- Click on the project code to open the collection
- Click on the Files tab on the collection page
- Select the files you want to download and click Download at the top of the page
- Select how you want to access the files from the drop down. If you are not logged in you will also need to supply an email address for notification
- Click Request files
You will receive an email when the data is available. This generally takes an hour or two.
You can then download the files as normal.
If you are accessing a large number of files use the Download via WebDAV option to get a link to all the files in the collection.
