The more commonly used RHESSI documents were moved from various web sites to the RHESSI doc directory in your local SSW installation so that they are now available when you are offline.  There is an index file at $SSW/hessi/doc/index.html to help you navigate the available documentation.

When you're online, links in the RHESSI Data & Software Center point to the same documents in hesperia's SSW installation.

Please let me know if there are more documents you would like to see moved to this area.
