Using the ATOA pipeline
The Australia Telescope Online Archive (ATOA) Pipeline is designed
for producing 'quick and dirty' images of data in the archive.
This allows you to get some idea of the data that is available, without
having to download and fully reduce it yourself.
Currently it can only reduce single pointing continuum data, but will
be extending to include spectral line data and possibly other modes.
The ATOA consists of over 1.5 terabytes of observation data
(approximately 50,000 RPFITS files) which has been collected from the
Australia Telescope Compact Array (ATCA) over the last 15 years.
More information about the archive is available
The pipeline and the archive have been developed as part of the ATNF
contribution to the
Australian Virtual Observatory.
Each stage of the pipeline is available as a web service, and hence it
can be reconfigured to suit the needs of various end users.

Running the pipeline
The current version of the pipeline is fully automatic.
This means once you have selected the data you wish to reduce,
all you have to do is wait for the results.
Any results or error messages will be returned to the screen, so it is
important you don't press 'STOP' or 'RELOAD' on your browser, as this
will interupt the process.
If you encounter any problems running the pipeline, please see the
Troubleshooting Guide and then contact
- Query: Enter query parameters on the
and click the Find button. This will return a list of matching
files from the archive.
- Select: Select the files you are interested
in reducing and click the Reduce button.
- Reduce: The reduction process will now start,
and feedback and errors will be displayed on the screen.
You may need to scroll down to see the latest updates as the pipeline runs.
When it is completed the resulting images (and some plots of the data)
will be available for download.
- Results: Download the FITS files (or plots)
by clicking on the links displayed and saving them to your machine.
