- O/IR System
As designed NIRI had two modes: (1) Imaging. Three plate scales are available. Altair is frequently combined with NIRI using the f/32 plate scale. The data reduction should be basically the same for all three plate scales. (2) Spectroscopy (no longer offered)
Various pdf tutorials for both imaging and spectroscopy reductions are available on the Gemini IRAF getting-started page. This page links to pdf cookbooks that can be downloaded. Information is available here on the NIRI data characteristics and electronic pattern noise. A presentation by Knut Olsen and Andrew Stephens on reducing both imaging and long slit spectroscopy data was given at the 2010 Gemini Data Workshop. The Workshop documentation provides raw and reduced data that can be downloaded. A presentation is also available by Cecilia Farina that was given on NIRI data at the 2011 South American Gemini Data Workshop.
The NIRI instrument page also includes a section on data reduction. This contains subsections: on the following topics:
