Introduction

UIST is a near-infrared imaging spectrometer at the UK Infrared Telescope. In addition to conventional imaging and long-slit spectroscopy modes UIST is capable of integral field spectroscopy (spectroscopy over a two dimensional field of view). The recipes, and calibration files described here are designed to allow automatic reduction of data from the UIST integral field unit (IFU) by the ORAC-DR pipeline.

It is intended that all of these recipes, while designed for use with UIST, are more generally applicable. It should be possible to use them to reduce data from other image-slicing IFUs with few modifications. Most of the information specific to UIST (positions of slice images on the array, order in which slices appear on the array, alignment of images etc.) is contained in calibration files.

This document is intended to be used by anyone who needs to reduce UIST IFU data or is involved in maintaining or updating these recipes and the associated calibration files. See SUN/230 for general ORAC-DR documentation, SUN/232 for information on ORAC-DR imaging data reduction and SUN/236 for information on ORAC-DR spectroscopy data reduction.
