In the period preceding an election for the House of Representatives, the Australian Government assumes a caretaker role (see the Guidance on Caretaker Conventions from the Department of Prime Minister and Cabinet). As this website is hosted by the Australian Astronomical Observatory (a division of the Department of Industry, Innovation & Science), content will be moderated from the time the House of Representatives is dissolved until after the election to ensure that political material is not placed on the site.
2dfdr is an automatic data reduction pipeline dedicated to reducing multi-fibre spectroscopy data, with current implementations for AAOmega (fed by the 2dF, KOALA-IFU, SAMI Multi-IFU or older SPIRAL front-ends), HERMES, 2dF (spectrograph), 6dF, and FMOS.
A graphical user interface is provided to control data reduction and allow inspection of the reduced spectra. It is being continually developed at the AAO in response to user feedback. You can reduce most of your data by simply pressing START AUTO REDUCTION in the Graphical User Interface.
The current publicly released version of 2dfdr is version 6.28 (Rockhopper). It is available via anonymous FTP for both Mac and Unix platforms. This release is described in detail in the 2dfdr Mailing List announcement linked at the bottom of this page. All users are warmly encouraged to subscribe to the 2dfdr mailing list to be informed of future updates and developments.
In general, the Mac OS versions will run on newer versions for which there is not an official release, but if you have trouble contact your support astronomer or the relevant instrument scientist.
In addition to the current public release, ongoing development is captured in beta releases, and occasionally it may be appropriate to use an older version for some situations. Your support astronomer or the instrument scientist for your instrument may recommend using one of these, otherwise the current public release is the best option for reducing data.
There are many resources to assist you in using 2dfdr. The best place to start is with the User Manual for the instrument corresponding to the data. All the resources available are listed below roughly in the order they should be consulted:
