On this page the address information of the Principal Investigator (PI) is entered. Although not all entries are marked as compulsory, this form should be filled in completely to make it easy for the XMM SOC to get in touch with the observer in case of need. A screen shot is shown in Fig. 8. The use of acronyms for the institute names (e.g., ``ESTEC'' instead of ``European Space Technology and Research Centre'') is permitted if necessary to save space.
