Extended Data Processing and Analysis Tools

The following list of tools and packages is intended as a guide for the Herschel Open Time Key Project Teams as they develop their own analysis plans. Note that many of the tools included here are still under development; this summary is not intended as a definitive list of packages available to the user.

The Herschel Instruments Page provides an overview as well as links to detailed information on each of the Observatory's instruments: HIFI PACS and SPIRE.
