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)

Some observations taken in specific observing modes have been fully reprocessed in a systematic way by experts after the release of the last Off-Line Processing pipeline (v10) released in 2003 and are now made available as 'Highly Processed Data Products' through the ISO Data Archive interface.

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.
The ISO-SWS Post-Helium Atlas of Near-Infrared Stellar spectra, July 2003, B. Vandenbussche et al.

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 But be aware that the reports sometimes reflect "work in progress" and may have been superseded.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.
