SWS Instrument Page

We recommend the ISO Handbook, Volume V: SWS - The Short Wavelength Spectrometer as a general reference point. Latest updates and further details on calibration can also be found in technical notes and publications available below.

Highly Processed Data Products (HPDP)

The following reprocessed data sets are available containing SWS observations made with ISO and are recommended for scientific usage:

• High resolution processed and defringed SWS01 spectra, January 2004, W. Frieswijk et al.

• Basic SWS Information

  • ISO Handbook, Volume V: SWS - The Short Wavelength Spectrometer, Version 2.0.1 (19/Apr/2004)
  • Version 10.1 of the ISO Off-Line Processing (OLP) software released (20/Nov/2001)
  • Observing with the ISO Short-Wavelength Spectrometer, Th. de Graauw et al., A&A, 315, L49-L54 (1996).
  • In-Orbit Performance of the ISO Short-Wavelength Spectrometer, Th. de Graauw et al., SPIE, 3354, 1204 (1998).

  Calibration

  Different aspects of the SWS calibration, which may be of relevance to future space missions are addressed in detail in the following papers:
  • "The Ground-Based Calibration of SWS" - H. Feuchtgruber et al.
  • "The ISO SWS Calibration: Strategy and Lessons Learned" - P. Roelfsema et al.
  • "SWS In-Flight Calibration" - R. Shipman et al.
  • "Stellar models in IR Calibration" - L. Decin
  • "Deglitching of SWS Low Resolution Data" - F. Lahuis et al.

  Additional SWS Documents

  These additional SWS documents describe aspects of the instrument in some detail and only need to be read for a deep understanding of a particular aspect. But be aware that the reports sometimes reflect "work in progress" and may have been superseded.

  See also the proceedings of several ISO Conferences and Meetings for specific instrument related topics.
