By agreement with the Swift Mission Project, proposers interested in making use of Swift time as part of their XMM-Newton science investigation may submit a single proposal in response to this XMM-Newton AO. The award of Swift time will be made to highly ranked XMM-Newton proposals and will be subject to approval by the Swift Project.
The primary criterion for the award of Swift time is that both XMM-Newton and Swift data are required to meet the scientific objectives of the proposal. Swift time will not be awarded without accompanying XMM-Newton observing time. The Swift Project is making up to 300 ks of Swift observing time available to such joint science proposals.
Swift observing time can be time-constrained, including coordinated observations and Targets of Opportunity. For coordinated and constrained observations, it is the proposer's responsibility to inform the Swift Science Operations Team of the observing time windows at least one week before observations start. Proposers must clearly describe how their proposal capitalizes on the unique capabilities of Swift. It is the responsibility of the proposer to demonstrate the feasibility of the proposed Swift observation (instrument modes, observing time and expected count rates from simulations or previous Swift observations). The requested time per Swift observation must be between a minimum of 1 ks and a maximum of 40 ks. Detailed technical information concerning Swift may be found at http://swift.gsfc.nasa.gov/proposals/appendix_f.html.
PIs are expected to determine if a target can be viewed by Swift (http://heasarc.gsfc.nasa.gov/Tools/Viewing.html) and whether bright stars prohibit the use of Swift UVOT (http://swift.gsfc.nasa.gov/proposals/bright_stars/bright_star_checker.html). PIs need to provide a strong justification for the choice of the filters if UVOT filters other than "filter of the day" are requested. If no strong justification is provided, all observations will be performed in "filter of the day" mode.
The Swift Guest Observer Facility will make feasibility assessments of the proposed observations independently of the XMM-Newton review. Proposed Swift observations determined to be infeasible will be rejected. Such a rejection could jeopardize the entire proposed science programme and impact the award of the XMM-Newton observing time as well.
If Swift time is approved, successful PIs will have to submit the standard Swift cover and target forms to the Swift Guest Observer Facility via ARK/RPS (https://heasarc.gsfc.nasa.gov/ark/swiftrps/) to provide the required information about observing strategy and instrument configurations.
Swift data sets obtained under this agreement will not be proprietary to the PI and immediately released publicly via the HEASARC data archive. No funds will be provided from the Swift Project for such joint XMM-Newton/Swift investigations.
Scientists can apply for the joint programme in the ``Observation Form'' of the XMM-Newton RPS. For each observation the PI has to specify the required observing time for both observatories. The ``Comment'' field should be used to briefly describe the Swift instrument modes and scheduling constraints.
