5 Proposal Submission and Optimisation

The proposal submission process for XMM-Newton is divided into two phases:

In response to the call, principal investigators (PIs) are asked to provide the scientific justification and some basic source and observing parameters, like coordinates, observation duration and observing mode of the prime instrument. This is done using the XIPS (XMM-Newton Interface for Proposal Submission) tool. Access to XIPS will be granted after the AO opening is announced in the XMM-Newton home page.

During the second phase of the process, the PIs of successful proposals must provide the exposure parameters in full detail via the Remote Proposal Submission software (XRPS). After submission each proposal undergoes a technical optimisation (the so called “proposal enhancement”) by SOC personnel. Note that it is the proposer's responsibility to ensure that the target coordinates (and, if necessary, the spacecraft position angle) are correct.

The technical optimisation of the proposals will consider the following points:

PIs will always be informed about the outcome of the evaluation described above. All changes of observation parameters have to be confirmed explicitly by the PIs.

This is a pre-condition for an observation to be included in the scheduling system (cf.
