How to use this manual depends on whether this is the first time you've processed any SWS data. If it is, read Chapters 3 to 8 of this manual, describing SWS, its performance and what scientific processing happens to data between the time it is telemetered down from ISO and the time it is put in the archive. Then read ``Getting started with SWS Data'', section 2.
If you've received SWS data before just read ``What's New'', section 1.3, and anything that it points to.
