Welcome to the website for the ORAC-DR Data Reduction Pipeline. ORAC-DR is an automated astronomical data reduction pipeline that reduces data from IRCAM, CGS4, UFTI, UIST, Michelle, and WFCAM at the United Kingdom Infrared Telescope, SCUBA and ACSIS (with the RxA3, HARP-B, and RxW front ends) at the James Clerk Maxwell Telescope, IRIS2 at the Anglo-Australian Telescope, INGRID from the William Herschel Telescope, Classic Cam from the Walter Baade Telescope, ISAAC and NACO from the VLT, and NIRI from Gemini. ORAC-DR can reduce sub-millimeter and infrared data taken in a wide variety of modes, including standard imaging and spectroscopy, polarimetry imaging and spectroscopy, and integral field spectroscopy.

For starters, you can download the latest version (created 2005-08-08), read the ChangeLog, and look at the SVN development statistics. ORAC-DR is also bundled with the humu release of the Starlink Software Collection, which is the recommended method for obtaining ORAC-DR. You can also view the SVN repository, or check out the tree by doing:

 % svn checkout https://www.oracdr.org/svn/trunk oracdr
