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 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 CVS development statistics. ORAC-DR is also bundled with the hokulei release of the Starlink Software Collection, which is the recommended method for obtaining ORAC-DR. We also have documentation available:

• SUN/230 - Overview and General Introduction (404K PS)
• SUN/231 - SCUBA Pipeline Data Reduction (313K PS)
• SUN/232 - Imaging Data Reduction User's Guide (1.1M PS)
• SUN/233 - Programmer's Guide (471K PS)
• SUN/236 - Spectroscopy Data Reduction (330K PS)
• SUN/246 - Integral Field Spectroscopy Data Reduction (286K PS)

Please also read about ORAC-DR from an astronomer's perspective.
