Instrument User Groups

In May 2003 Instrument User Groups have been appointed to advise the NOT Director and STC on the current performance of the instrumentation at NOT, and on the desirability and priorities of instrument upgrades in the short and long term. The Instrument User Groups and their fields of responsibility are:

• Optical Imaging: Chair: H. Dahle, Oslo (Chair), J. Hjorth (Copenhagen), G. Östlin (Stockholm), and T. Pursimo (NOT)
• Near-IR Imaging: J. Kotilainen, Turku (Chair), A. Djupvik (NOT) and B. Thomsen (Aarhus)
• Optical and Near-IR Low-Resolution Spectroscopy: J. Fynbo, Copenhagen (Chair), T. Augusteijn (NOT), and N. Ryde (Uppsala)
• High-Resolution Optical Spectroscopy: T. Hackman, Helsinki (Chair), S. Frandsen (Aarhus), N. Piskunov (Uppsala), and J. Telting (NOT).
