This page is used to enter relevant information for the Principal Investigator (PI). To make easier for the XMM-Newton SOC to get in touch with the observer in case of need, this form should be filled in completely. It is extremely important that the ''email'' address is correct and up-to-date. An error message will be issued for incorrect, e.g. incomplete, email addresses. This is to make sure that the PIs receive the acknowledgement email after submission of their proposal. As all future interaction and communication between the PI and the SOC will be based on this email address, the use of an institutional email is strongly recommended. A warning message will be issued for obviously non-institutional email addresses, like e.g. gmail.
For some programs, if several PIs were introduced during Phase I of proposal submission, they will appear in the left frame of the XRPS navigation tool Fig. 7 (see Section 4.4.2). Only the first PI in this list has editting permissions and will be the recipient of the ''Technical Evaluation'' (see § 5.6) and Proposal Submission (see Section 5.7) confirmation emails.
''First Name'' and ''Surname'' of the PI cannot be changed. A screen shot is shown in Fig. 6. The use of acronyms for the institute names (e.g., ''ESAC'' instead of ''European Space Astronomy Centre'') is permitted if necessary to save space.
Unlike for the Co-I where at the bottom of the details page there are two buttons, ''Add Co-I'' and ''Delete Co-I Entry'' from the list, for proposals with several PIs, these two actions are not permitted and only the PI details can be modified.
