XMM-Newton Target of Opportunity (ToO)

ToO Policies & Procedures

Targets of Opportunity (ToOs) are subject to the policies and procedures explained in the XMM-Newton Policies & Procedures Document which is available online (or can be downloaded from here).
Please, pay particular attention to Section 5.2.2 and especially Subsection 5.2.2.2, which makes reference to unanticipated ToO alerts explaining also the policy for the determination of proprietary periods of such observations.

"Discretionary Time” may be granted for programmes where a timely observation (outside of the normal announcement of opportunity cycle) is likely to result in a significant scientific impact.

ToO Alert

Investigators may notify the XMM-Newton SOC of a Target of Opportunity online. Simply complete the details on the ToO Notification Page.

Pending Anticipated ToOs

A list of anticipated ToO observations already accepted by the XMM-Newton Observing Time Allocation Committee (OTAC), which are currently not yet fulfilled, is available at this link.

Unanticipated ToO Details

The following list comprises approved and performed unanticipated ToOs.

The status of the data is denoted using the following acronyms:

ToO (public): Target of Opportunity data are public with respect to data-rights
ToO (DD-MMM-YYYY): Target of Opportunity data are public after the given date, usually after a proprietary period of half a year. Dates can also be linked to data-rights of another accepted open-time target, or be decided by the Project Scientist
ToO (TBD): Target of Opportunity data rights are granted, but the date for the observation to be public is still undefined. Either the ODF has not been delivered yet, or the data rights depend on another observation
DPS: Observed in Discretionary Time of the Project Scientist

The links from entries in this table are as follows:

Rev: link to the Orbit/Date Calculator, to check the observation date
Observation Id: link to the corresponding entry in the Observation Log, if already scheduled. If an observation is not yet listed, the scheduling is still to be confirmed
ODF Data: link to the ODF data for download from the XSA archive, when available (the typical production time for an ODF is approximately 2 weeks). If the data is still proprietary, the linked page will indicate this
PPS Data: link to the PPS data for download from the XSA archive, when available (the typical production time for PPS Data is approximately 6 weeks). If the data is still proprietary, the linked page will indicate this

This table is weekly updated, but there might be periods for which updates take slightly longer. Should you need to know details about a ToO/DPS observation, that are not given below (yet), please do not hesitate to contact the HelpDesk.
