The Users' Handbook is an integral part of the SOC's web-based online information system and it contains lots of links to other components of the web server. All links can also always be reached via the SOC home page.
Additionally, in order to facilitate the search for more information, § 8 of this document contains a compilation of relevant links and references.
The contact address for users who need help or additional information, or who want to send suggestions to improve our system, is xmmhelp@astro.estec.esa.nl. All questions relating to AO and observing matters should be directed to this account. The SOC plans to collect users' questions and list them in a file with Frequently Asked Questions (FAQs). A link to this file will then be added here.
