ORAC-DR – spectroscopy data reduction
ORAC-DR is a general-purpose automatic data-reduction pipeline environment. This document describes its use to reduce spectroscopy data collected at the United Kingdom Infrared Telescope (UKIRT) with the CGS4, UIST and Michelle instruments, at the Anglo-Australian Telescope (AAT) with the IRIS2 instrument, and from the Very Large Telescope with ISAAC. It outlines the algorithms used and how to make minor modifications of them, and how to correct for errors made at the telescope.
