Important information

The complete Parkes Pulsar Data Users Guide is available at


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:

Source name/position

Source Name

The pulsar's J name (position in the celestial sphere) that provides more precise coordinates of its location in the sky.

Right Ascension

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.

Search Window

Number of minutes of arc, forming a search radius from the central point.


Project ID

An identification code given to observing projects granted time at the Parkes Observatory.

Observation Date

UTC (Coordinated Universal Time) / MJD (Modified Julian Date) start of the observation. (MJD: days from 17 November, 1858).


Search by the filename


Frequency (MHz)

Radio astronomy is a sub-field of astronomy that studies celestial objects at radio frequencies. This field is the centre frequency of the observation.

Band Name

The wavelength of the centre frequency.

Observation Mode

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.

Configure Columns

The configure columns button allows the users to configure which columns and fields will be displayed in the search results page.

Refine search

This functionality allows users to go back to the search page with all the populated fields from the last search retained.

Filter results

This functionality can be used to further filter on the search results by using some filter facets such as 

  • Source Name
  • Project ID
  • Backend
  • Observation Type
  • Frontend
  • Frequency
  • Calibration Files

Configure columns

The configure columns functionality allows the users to configure which columns and fields will be displayed in the search results page.
